.3

If Parity disable mode (PEN = 0),

location of the 9th data bit to be transmitted in UART mode 2 ("0" or "1"). If Parity enable mode (PEN = 1),

even/odd parity selection bit for transmit data in UART mode 2.

0:Even parity bit generation for transmit data

1:Odd parity bit generation for transmit data

.2

.1

.0

If Parity disable (PEN = 0),

location of the 9th data bit that was received in UART mode 2 ("0" or "1"). If Parity enable mode (PEN = 1),

even/odd parity selection bit for receive data in UART mode 2.

0:Even parity check for the received data

1:Odd parity check for the received data

A result of parity error will be saved in RPE bit of the UARTPND register after parity checking of the received data.
