Received data does not. Baud Rate Registers Control Refer to UART chapter for operation Driver Enable Polarity 0 = DE signal is active High 1 = DE signal is active Low Multiprocessor Bit Transmit 0 = Send a 0 as the multiprocessor bit 1 = Send a 1 as the multiprocessor bit Multiprocessor Mode [0] See Multiprocessor Mode [1] below Multiprocessor (9-bit) Enable 0 = Multiprocessor mode is disabled 1 = Multiprocessor mode is enabled Multiprocessor Mode [1] with Multiprocess Mode bit 0: 00 = Interrupt on all received bytes 01 = Interrupt only on address bytes 10 = Interrupt on address match and following data 11 = Interrupt on data following an address match UART1 Status 1 U0STAT1 (F4CH - Read Only) D7 D6 D5 D4 D3 D2 D1 D0 Mulitprocessor Receive Returns value of last multiprocessor bit New Frame 0 = Current byte is not start of frame 1 = Current byte is start of new frame Reserved UART1 Address Compare U0ADDR (F4DH - Read/Write) D7 D6 D5 D4 D3 D2 D1 D0 UART1 Address Compare [7:0] UART1 Baud Rate Generator High Byte U0BRH (F4EH - Read/Write) D7 D6 D5 D4 D3 D2 D1 D0 UART1 Baud Rate divisor [15:8] UART1 Baud Rate Generator Low Byte U1BRL (F4FH - Read/Write) D7 D6 D5 D4 D3 D2 D1 D0 UART1 Baud Rate divisor [7:0] I2C Data I2CDATA (F50H - Read/Write) D7 D6 D5 D4 D3 D2 D1 D0 I2C data [7:0] I2C Status I2CSTAT (F51H - Read Only) D7 D6 D5 D4 D3 D2 D1 D0 NACK Interrupt 0 = No action required to service NAK 1 = START/STOP not set after NAK Data Shift State 0 = Data is not being transferred 1 = Data is being transferred Transmit Address State 0 = Address is not being transferred 1 = Address is being transferred Read 0 = Write operation 1 = Read operation 10-Bit Address 0 = 7-bit address being transmitted 1 = 10-bit address being transmitted Acknowledge 0 = Acknowledge not transmitted/received 1 = For last byte, Acknowledge was transmitted/received Receive Data Register Full 0 = I2C has not received data 1 = Data register contains received data Transmit Data Register Empty 0 = Data register is full 1 = Data register is empty |
