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-
AUTO / AWS-AUTO firmware and acts depending on the function implemented.
The following GPIOs are available on the UC864-E-AUTO / AWS-AUTO:
