Value
Each bit corresponds to one GPIO port C pin (GPIO64-GPIO95)
0 Reading a 0 indicates that the state of the pin is currently low, irrespective of the mode for which
the pin is configured.
Writing a 0 will force an output of 0 if the pin is configured as a GPIO output in the appropriate
GPCMUX1/2 and GPCDIR registers; otherwise, the value is latched but not used to drive the pin.
1 Reading a 1 indicates that the state of the pin is currently high irrespective of the mode for which
the pin is configured.
Writing a 1 will force an output of 1 if the pin is configured as a GPIO output in the GPCMUX1
and GPCDIR registers; otherwise, the value is latched but not used to drive the pin.
