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 UC864-E firmware and acts depending on the function
implemented.
The following GPIO are available on the UC864-E module:
Pin Signal I/O Function Type
