GEN Module
Inputs
An input that provides one or more input signals to different blocks in the chip is
always connected to those blocks. The target block must be configured to use the
input; similarly, those blocks that should not use the input must be configured not to
use it.
Outputs
Configuring a pin for an output function also enables the tri-state driver for that pin.
There should be no external driver on a pin configured for output.
