TXD—Transmit Data
UART transmitter data byte to be shifted out through the TXDx pin.
Data bytes received through the RXDx pin are stored in the UART Receive Data register
(Table
with the Write-only UART Transmit Data register.
RXD—Receive Data
UART receiver data byte from the RXDx pin
The UART Status 0 and Status 1 registers
current UART operating configuration and status.
RDA—Receive Data Available
This bit indicates that the UART Receive Data register has received data. Reading the
UART Receive Data register clears this bit.
0 = The UART Receive Data register is empty.
1 = There is a byte in the UART Receive Data register.
