I have three questions about GIO port set:
1: GIO input mode : opendrain + pullup/pulldown, what will happen? Will pullup/pulldown effect the input data?
2: GIO input mode : set the OUTPUT register, what will happen ?Will the output data effect the input data and the output data?
3: GIO output mode : opendrain + pullup/pulldown, what will happen?Will pullup/pulldown effect the input data?
