10 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 GE864-QUAD / PY firmware and acts depending on the function implemented. For Logic levels please refer to chapter 7.

The following GPIO are available on the GE864-QUAD and GE864-PY:
