• '''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:

<br> === Input Enable === INPUTENABLE = 0: Input Disable. Pin is configured in output only mode.  INPUTENABLE = 1: Input Enable. Pin is configured in bidirectional mode.  NOTE: For proper functioning of some peripherals INPUTENABLE must be set to 1 for pads configured to drive output clocks:

IgepV2 Board have a default mux configuration, but some cases is necessary change it, for example your project need UART2 at j990 connector to transmit data, for this purpose you need change some mux configurations to enable it and be sure that this modification don't break or interferes in other IC or peripherals. The mux options are vast.
