6.3.1.12.76 Pad Configuration Register 132 (SIU_PCR132)
The SIU_PCR132 register controls the pin function, direction, and static electrical attributes of the
ETPUA[18]_PCSD[3]_GPIO[132] pin.
Figure 6-88. ETPUA[18]_PCSD[3]_GPIO[132] Pad Configuration Register (SIU_PCR132)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.77 Pad Configuration Register 133 (SIU_PCR133)
The SIU_PCR133 register controls the pin function, direction, and static electrical attributes of the
ETPUA[19]_PCSD[4]_GPIO[133] pin.

When configured as PCS, the OBE bit has no effect. The OBE bit must be set to 1 for ETPUA of GPIO when configured as
outputs.

The IBE bit must be set to 1 for ETPUA or GPIO when configured as inputs. When configured as PCS, ETPUA, or GPO outputs,
set the IBE bit to 1 to reflect the pin state in the corresponding GPDI register.
