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
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
PE—Parity Error
This bit indicates that a parity error has occurred. Reading the UART Receive Data
register clears this bit.
0 = No parity error has occurred
1 = A parity error has occurred
OE—Overrun Error
This bit indicates that an overrun error has occurred. An overrun occurs when new data is
63). The read-only UART Receive Data register shares a Register File address with
