The functional bits of a pad configuration register field are divided into the following five fields:

- • MUXMODE (3 bits) defines the multiplexing mode applied to the pin. A mode corresponds to the selection of the functionality mapped on the pin with six (0 to 5) possible functional modes for each pin.

- • PULL (2 bits) for combinational pullup/pulldown configuration:

-> PULLTYPESELECT: Pullup/pulldown selection for the pin.

-> PULLUDENABLE: Pullup/pulldown enable for the pin.

- • INPUTENABLE (1 bit) drives an input enable signal to the I/O CTRL.

-> INPUTENABLE = 0: Input Disable. Pin is configured in output only mode.

-> INPUTENABLE = 1: Input Enable. Pin is configured in bidirectional mode.

- • Off mode values (5 bits) override the pin state when the OFFENABLE bit CONTROL. This feature is used for power saving management:

->OFFENABLE: Off mode pin state override control. Set to 1 to enable the feature and to 0 to disable it.

->OFFPULLUDENABLE: Off mode pullup/pulldown enable.

-&gt;OFFPULLTYPESELECT: Off mode pullup/pulldown selection. • Wake-up bits (2 bits): -&gt;WAKEUPENABLE: Enable wake-up detection on input. It is also the off mode input enable value.<br> -&gt;WAKEUPEVENT: Wake-up event status for the pin.<br>
