When configured as ETPUA output or GPO, the OBE bit should be set to one.
2
When configured as ETPUA output, DSPI_C_PCS[4], ETPU_A[13] or GPO, the IBE bit may be set to one to reflect
the pin state in the corresponding GPDI register. Setting the IBE bit to zero reduces power consumption. The IBE
bit must be set to one for ETPUA or GPIO when configured as input.
3
The weak pull up/down selection at reset for the ETPU_A[31] pin is determined by the WKPCFG pin.

In cases where an I/O function can be either an input or an output, I/O direction is specified using the IBE and OBE
bits. Set IBE = 1 for input or OBE = 1 for output.
2
For I/O functions that change direction dynamically, such as the external data bus, switching between input and
output is handled internally and the IBE and OBE bits are ignored.

When configured as ETPU, the IBE bit may be set to one to reflect the pin state in the corresponding GPDI register.
Setting the IBE bit to zero reduces power consumption. The IBE bit must be set to one for both EMIOS[0] and
GPIO[179] when configured as inputs.
