12. 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 HE863 Family firmware and acts depending on the function
implemented.
The following GPIOs are available on the HE863 Family.
