Refer to Table 6-19 for bit field definitions. Table 6-91 lists the PA fields for
ETPUA[22]_IRQ[10]_GPIO[136].
6.3.1.92 Pad Configuration Register 137 (SIU_PCR137)
The SIU_PCR137 register controls the function, direction, and electrical attributes of
ETPUA[23]_IRQ[11]_GPIO[137]. Both the input and output channels of ETPUA[23] are connected.

Refer to Table 6-19 for bit field definitions. Table 6-92 lists the PA fields for
ETPUA[23]_IRQ[11]_GPIO[137].

When configured as IRQ[11], the OBE bit has no effect. The OBE bit must be set to one for ETPUA[23] or GPIO[137] when
configured as outputs.

When the pad is configured as an output, set the IBE bit to 1 to show the pin state in the GPDI register. Clear the IBE bit to 0
to reduce power consumption. The IBE bit must be set to 1 for ETPUA[23] or GPIO[137] when configured as inputs.

The weak pullup/down selection at reset for the ETPUA[23] pin is determined by the WKPCFG pin.
