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 be read; they 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
GE866-QUAD firmware and acts depending on the function
implemented.
For Logic levels please refer to chapter 8.
The following table shows the available GPIO on the GE866-
QUAD.
