Refer to Table 6-19 for bit field definitions. Table 6-85 lists the PA fields for
ETPUA[11]_ETPUA[23]_GPIO[125].
6.3.1.86 Pad Configuration Register 126 (SIU_PCR126)
The SIU_PCR126 register controls the function, direction, and electrical attributes of
ETPUA[12]_PCSB[1]_GPIO[126].

When configured as PCSB[1], the OBE bit has no effect. The OBE bit must be set to 1 for ETPUA[12] or GPIO[126] when
configured as outputs.

The IBE bit must be set to 1 for ETPUA[12] or GPIO[126] when configured as inputs. When the pad is configured as an output,
set the IBE bit to 1 to show the pin state in the GPDI register.
