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 GE864-QUAD
V2 / GE864-DUAL V2 firmware and acts depending on the function implemented.
The following GPIO are available on the GE864-QUAD V2 / GE864-DUAL V2:
