Px Pin[n] Output Value
Each of these bits controls the status of a GPIO pin when the GPIO pin is configured
as output, open-drain or quasi-bidirectional mode.
1 = GPIO port [A/B] Pin[n] will drive High if the corresponding output mode bit is set.
0 = GPIO port [A/B] Pin[n] will drive Low if the corresponding output mode bit is set.
