UART0PX
Serial Port 0 RX/TX Pin Exchange
0 = Assign UART0 RXD to multiple I/O pin RXD
UART0 TXD to multiple I/O pin TXD
1 = Assign UART0 RXD to multiple I/O pin TXD
UART0 TXD to multiple I/O pin RXD
Note:
that Pin direction is controlled by I/O type of relative pin.
RXD/TXD will exchange immediately once setting or clearing this bit. User should take care
of not exchanging pins during transmission or receiving. Or it may cause unpredictable
situation and no warning alarms.
