URXPEN: UART RX parity bit check function control bit.
0 = Disable UART RX parity bit check function. The data stream doesn’t include parity bit.
1 = Enable UART RX parity bit check function. The data stream includes parity bit.
URXPS: UART RX parity bit format control bit.
0 = UART RX parity bit format is even parity.
1= UART RX parity bit format is odd parity.
URXPC: UART RX parity bit checking status bit.
0 = UART RX parity bit checking is error.
1 = UART RX parity bit checking is correct.
URXM: UART RX data buffer length control bit.
0 = 1-byte.
