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
the 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.
PE—Parity Error
This bit indicates that a parity error has occurred. Reading the UART Receive Data Regis-
ter 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
received and the UART Receive Data Register has not been read. If the RDA bit is reset to
53). The Read-only UART Receive Data Register shares a Register File address
