11. General Purpose I/O
The general-purpose I/O pads can be configured to act in three different ways:

Input

Output

Alternate function (internally controlled)
Input pads can only be read and report the digital value (high or low) present on the pad at the
read time; output pads can only be written or queried and set the value of the pad output; an
alternate function pad is internally controlled by the GE/GC864-QUAD V2 and GE864-
GPSfirmware and acts depending on the function implemented.
The following GPIO are available on the GE/GC864-QUAD V2 and GE864-GPS:
