-&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>'''

'''NOTE: Off mode can be configured like pin output with a HIGH&nbsp;or LOW value or pin input with wake-up detection feature.'''

'''NOTE: For input pins, OFFOUTENABLE and OFFOUTVALUE bits can not be configured.'''<br>

'''The safe mode''' (default mode 7) avoids any risk of electrical contention by configuring the pin as an input with no functional interface mapped to it. The safe mode is used mainly as the default mode for all pins containing no mandatory interface at the release of power-on reset.

<br> NOTE: For most pads, the reset value for the MUXMODE field is 0b111. The exceptions are pads to be used at boot time to transfer data from selected peripherals to the external flash memory.

=== 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:

*SDRC*GPMC*McSPIi*I2Ci*MMCi*McBSPi

*HSUSB HOST

=== <br> '''IGEPv2<br> ''' === 

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.
