The device configuration registers include a set of four consecutive interrupt source registers that provides interrupt-status for all 8 UARTs, timer/counter and a sleep wake up indicator. Each UART channel has its own 16550 UART compatible configuration register set for individual channel control, status, and data transfer. Additionally, each UART channel has 64-byte of transmit and receive FIFOs, automatic RTS/CTS or DTR/DSR hardware flow control with hysteresis control, automatic Xon/Xoff and special character software flow control, programmable transmit and receive FIFO trigger levels, FIFO level counters, infrared encoder and decoder (IrDA ver. 1.0), programmable baud rate generator with a prescaler of divide by 1 or 4, and data rate up to 6.25 Mbps with 8X sampling clock or 3.125Mbps with 16X sampling clock. The XR16L788 is a 5V and 3.3V device with 5 volt tolerant inputs (except XTAL1).2.0FUNCTIONAL DESCRIPTIONS2.1Device Reset2.1.1Hardware ResetThe RST# input resets the internal registers and the serial interface outputs in all 8 channels to their default state (see Table 19). A LOW pulse of longer than 40 ns duration will be required to activate the reset function in the device.2.1.2Software ResetThe internal registers of each UART can be reset by writing to the RESET register in the Device Configuration Registers. For more details, see the RESET register description on page 25.2.2UART Channel SelectionThe UART provides the user with the capability to bi-directionally transfer information between an external CPU and an external serial communication device. A logic 0 on the chip select pins, CS#, allows the user to select one of the UART channels to configure, send transmit data and/or unload receive data to/from the UART. When address line A7 = 0, address lines A6:A4 are used to select one of the eight channels. See Table 1 below for UART channel selection.T ABLE 1: UART C HANNEL S ELECTIONA7A6A5A4F UNCTION0000Channel 0 Selected0001Channel 1 Selected0010Channel 2 Selected0011Channel 3 Selected0100Channel 4 Selected0101Channel 5 Selected0110Channel 6 Selected0111Channel 7 Selected2.3Simultaneous Write to All ChannelsDuring a write cycle, the setting of REGB bit-0 to a logic 1 will override the channel selection of address A6:A4 and allow a simultaneous write to all 8 UART channels when any channel is written to. This functional capability allow the registers in all 8 UART channels to be modified concurrently, saving individual channel initialization time. Caution should be considered, however, when using this capability. Any in-process serial data transfer may be disrupted by changing an active channel’s mode. Also, REGB bit-0 should be reset to a logic 0 before attempting to read from the UART.7XR16L788xrHIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART REV. 1.2.282.4INT# OuputThe INT# interrupt output changes according to the operating mode and enhanced features setup. Table 2and 3 summarize the operating behavior for the transmitter and receiver.2.5CRYSTAL OSCILLATOR / BUFFERThe 788 includes an on-chip oscillator (XTAL1 and XTAL2). The crystal oscillator provides the system clock to the Baud Rate Generators (BRG) in each of the 8 UARTs, the 16-bit general purpose timer/counter and internal logics. XTAL1 is the input to the oscillator or external clock buffer input with XTAL2 pin being the output. For programming details, see “Section 2.6, Programmable Baud Rate Generator” on page 9.The on-chip oscillator is designed to use an industry standard microprocessor crystal (parallel resonant, fundamental frequency with 10-22 pF capacitance load, ESR of 20-120 ohms and 100ppm frequency tolerance) connected externally between the XTAL1 and XTAL2 pins (see Figure 3). Alternatively, an external clock can be connected to the XTAL1 pin to clock the internal 8 baud rate generators for standard or custom rates. Typically, the oscillator connections are shown in Figure 3.

T YPICAL OSCILLATOR CONNECTIONSxr XR16L788 REV. 1.2.2HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART2.6Programmable Baud Rate GeneratorA single Baud Rate Generator (BRG) is provided for the transmitter and receiver, allowing independent TX/RX channel control. The programmable Baud Rate Generator is capable of operating with a crystal frequency of up to 24 MHz. However, with an external clock input on XTAL1 pin and a 2K ohms pull-up resistor on XTAL2 pin (as shown in Figure 4) it can extend its operation up to 50 MHz (3.125 Mbps serial data rate) at room temperature and 5.0V.F IGURE 4. E XTERNAL C LOCK CEach UART has its own Baud Rate Generator (BRG) with a prescaler for the transmitter and receiver. The prescaler is controlled by a software bit in the MCR register. The MCR register bit-7 sets the prescaler to divide the input crystal or external clock by 1 or 4. The output of the prescaler clocks to the BRG. The BRG further divides this clock by a programmable divisor between 1 and (216 -1) to obtain a 16X or 8X sampling clock of the serial data rate. The sampling clock is used by the transmitter for data bit shifting and receiver for data sampling. The BRG divisor (DLL and DLM registers) defaults to a random value upon power up. Therefore, the BRG must be programmed during initialization to the operating data rate.F IGURE 5. B AUD R ATEG ENERATOR9XR16L788xrHIGH PERFORMANCE 2.97V TO 5.5V OCTAL UARTREV. 1.2.210Programming the Baud Rate Generator Registers DLM and DLL provides the capability of selecting the operating data rate. Table 4 shows the standard data rates available with a 14.7456 MHz crystal or external clock at 16X clock rate. At 8X sampling rate, these data rates would double. When using a non-standard data rate crystal or external clock, the divisor value can be calculated for channel ‘N’ with the following equation(s).2.7TransmitterThe transmitter section comprises of an 8-bit Transmit Shift Register (TSR) and 64 bytes of FIFO which includes a byte-wide Transmit Holding Register (THR). TSR shifts out every data bit with the 16X internal clock. A bit time is 16 clock periods (see EMSR bit-7). The transmitter sends the start-bit followed by the number of data bits, inserts the proper parity-bit if enabled, and adds the stop-bit(s). The status of the FIFO and TSR are reported in the Line Status Register (LSR bit-5 and bit-6).2.7.1Transmit Holding Register (THR) - Write OnlyThe transmit holding register is an 8-bit register providing a data interface to the host processor. The host writes transmit data byte to the THR to be converted into a serial data stream including start-bit, data bits, parity-bit and stop-bit(s). The least-significant-bit (Bit-0) becomes first data bit to go out. The THR is the input register to the transmit FIFO of 64 bytes when FIFO operation is enabled by FCR bit-0. Every time a write operation is made to the THR, the FIFO data pointer is automatically bumped to the next sequential data location.2.7.2Transmitter Operation in non-FIFO ModeThe host loads transmit data to THR one character at a time. The THR empty flag (LSR bit-5) is set when the data byte is transferred to TSR. THR flag can generate a transmit empty interrupt (ISR bit-1) when it is enabled by IER bit-1. The TSR flag (LSR bit-6) is set when TSR becomes completely empty.divisor (decimal) = (XTAL1 clock frequency / prescaler) / (serial data rate x 16), WHEN 8XMODE-BIT N IS 0 divisor (decimal) = (XTAL1 clock frequency / prescaler) / (serial data rate x 8), WHEN 8XMODE-BIT N IS 1T ABLE 4: T YPICAL DATA RATES WITH A 14.7456 MH Z CRYSTAL OR EXTERNAL CLOCK AT 16X S AMPLINGO UTPUT Data Rate MCR Bit-7=1O UTPUT Data Rate MCR Bit-7=0D IVISOR FOR 16x Clock (Decimal)D IVISOR FOR 16x Clock (HEX)DLM P ROGRAMV ALUE (HEX)DLL P ROGRAM V ALUE (HEX)D ATA R ATE E RROR (%)100400230490009 000600240038418001 80012004800192C000 C0024009600966000 600480019.2k 483000 300960038.4k 241800 18019.2k 76.8k 120C 00 0C 038.4k 153.6k 60600 06057.6k 230.4k 40400 040115.2k 460.8k 20200 020230.4k921.6k1010001F IGURE 6. T RANSMITTER O PERATION IN NON-FIFO M ODE2.7.3Transmitter Operation in FIFO ModeThe host may fill the transmit FIFO with up to 64 bytes of transmit data. The THR empty flag (LSR bit-5) is set whenever the FIFO is empty. The THR empty flag can generate a transmit empty interrupt (ISR bit-1) when the amount of data in the FIFO falls below its programmed trigger level. The transmit empty interrupt is enabled by IER bit-1. The TSR flag (LSR bit-6) is set when TSR/FIFO becomes empty.F IGURE 7. T RANSMITTER O PERATION IN FIFO AND F LOW C ONTROL M ODE2.8ReceiverThe receiver section contains an 8-bit Receive Shift Register (RSR) and 64 bytes of FIFO which includes a byte-wide Receive Holding Register (RHR). The RSR uses the 16X for timing. It verifies and validates every bit on the incoming character in the middle of each data bit. On the falling edge of a start or false start bit, an internal receiver counter starts counting at the 16X. After 8 clocks the start bit period should be at the center of the start bit. At this time the start bit is sampled and if it is still a logic 0 it is validated. Evaluating the start bit in this manner prevents the receiver from assembling a false character. The rest of the data bits and stop bits are sampled and validated in this same manner to prevent false framing. If there were any error(s), they are reported in the LSR register bits 2-4. Upon unloading the receive data byte from RHR, the receive FIFO pointer is bumped and the error tags are immediately updated to reflect the status of the data byte in RHR register. RHR can generate a receive data ready interrupt upon receiving a character or delay until it reaches the FIFO trigger level. Furthermore, data delivery to the host is guaranteed by a receive data ready time-out interrupt when data is not received for 4 word lengths as defined by LCR[1:0] plus 12 bits time. This is equivalent to 3.7-4.6 character times. The RHR interrupt is enabled by IER bit-0.HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART REV. 1.2.2 2.8.1Receive Holding Register (RHR) - Read-OnlyThe Receive Holding Register is an 8-bit register that holds a receive data byte from the Receive Shift Register. It provides the receive data interface to the host processor. The RHR register is part of the receive FIFO of 64 bytes by 11-bits wide, the 3 extra bits are for the 3 error tags to be reported in LSR register. When the FIFO is enabled by FCR bit-0, the RHR contains the first data character received by the FIFO. After the RHR is read, the next character byte is loaded into the RHR and the errors associated with the current data byte are immediately updated in the LSR bits 2-4.F IGURE 8.

The THR and RHR for channels 0 to 7 are located at address 0x00, 0x10, 0x20, 0x30, 0x40, 0x50, 0x60 and 0x70 respectively. Transmit data byte is loaded to the THR when writing to that address and receive data is unloaded from the RHR register when reading that address. Both THR and RHR registers are 16C550 compatible in 8-bit format, so each bus operation can only write or read in bytes..T ABLE 5: T RANSMIT AND R ECEIVE H OLDING R EGISTER L OCATIONS, 16C550 COMPATIBLE2.10Automatic RTS/DTR Hardware Flow Control OperationAutomatic RTS/DTR flow control is used to prevent data overrun to the local receiver FIFO. The RTS#/DTR# output pin is used to request remote unit to suspend/resume data transmission. The flow control features are individually selected to fit specific application requirement (see Figure 10):•Select RTS (and CTS) or DTR (and DSR) through MCR bit-2.•Enable auto RTS/DTR flow control using EFR bit-6.•The auto RTS or auto DTR function must be started by asserting the RTS# or DTR# output pin (MCR bit-1 or bit-0 to a logic 1, respectively) after it is enabled.•If using programmable RX FIFO trigger levels, hysteresis levels can be selected via FCTR bits 3-0.With the Auto RTS function enabled, the RTS# output pin will not be de-asserted (HIGH) when the receive FIFO reaches the programmed trigger level, but will be de-asserted when the FIFO reaches the next trigger level for Trigger Tables A-C (See Table 14). The RTS# output pin will be asserted (LOW) again after the FIFO is unloaded to the next trigger level below the programmed trigger level.HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART REV. 1.2.2 For Trigger Table D (or programmable trigger levels), the RTS# output pin is de-asserted when the the RX FIFO level reaches the RX trigger level plus the hysteresis level and is asserted when the RX FIFO level falls below the RX trigger level minus the hysteresis level.However, even under these conditions, the 788 will continue to accept data until the receive FIFO is full if the remote UART transmitter continues to send data.•If used, enable RTS/DTR interrupt through IER bit-6 (after setting EFR bit-4). The UART issues an interrupt when the RTS#/DTR# pin makes a transition: ISR bit-5 will be set to 1.2.10.1Auto CTS/DSR Flow ControlAutomatic CTS/DSR flow control is used to prevent data overrun to the remote receiver FIFO. The CTS/DSR pin is monitored to suspend/restart local transmitter. The flow control features are individually selected to fit specific application requirement (see Figure 10):•Select CTS (and RTS) or DSR (and DTR) through MCR bit-2.•Enable auto CTS/DSR flow control using EFR bit-7.With the Auto CTS or Auto DTR function enabled, the UART will suspend transmission as soon as the stop bit of the character in the Transmit Shift Register has been shifted out. Transmission is resumed after the CTS#/ DTR# input is re-asserted (logic 0), indicating more data may be sent.•If used, enable CTS/DSR interrupt through IER bit-7 (after setting EFR bit-4). The UART issues an interrupt when the CTS#/DSR# pin makes a transition: ISR bit-5 will be set to a logic 1, and UART will suspend TX transmissions as soon as the stop bit of the character in process is shifted out. Transmission is resumed after the CTS#/DSR# input returns LOW, indicating more data may be sent.。

z BCC(块校验字符)用于检查通讯数据的准确性 z BCC校验如果有错,接收仪表将没有应答 z 有下面4种类型的BCC校验
(1)BCC 加（Add）加法操作是从起始字符到结束字符的求和例1 : BCC加和读指令(读):
STX 0 1 1 R 0 1 0 0 9 ETX E 3 CR LF
02H +30H +31H +31H +52H +30H +31H +30H +30H +39H +03H = 1E3H 得到最后校验位(1E3H)=E3H 即: “E”=45H, : “3”=33H
址符合,接收字符格式和校验正确后,才能进行正常的通讯。
