6.5.5.1.2 Remappable Input Priority
The user can select only one single pin for any of the remappable peripheral inputs. There is no need for priority encoding for RP inputs.
In this way, it is possible to drive a remappable output function on an RPx pin and a completely different remappable input function on the same pin. This can be useful, for instance, in driving an EVSYS output back into a Timer clock or gating input by assigning both functions to the same remap pin.
For proper operation, the software must ensure that the unused group register offset of a (repeated) input function is programmed to 4’h0
. Failure to do so leads to unknown behavior.
