 		 #41669 - RE: change p3.1 from txd to nomal i/o pin
Responding to: ???'s previous message

You dont do anything!!

If you dont have any code for the UART and power up the MCU, the pin p3.1 just initializes with a 1 written to it by default - you can use it as a Input pin. If you now want to write a 1 or 0 - simply do it and it will become an Output pin. Great is it not?
