6.3.1.12.74 Pad Configuration Register 130 (SIU_PCR130)
The SIU_PCR130 register controls the pin function, direction, and static electrical attributes of the
ETPUA[16]_PCSD[1]_GPIO[130] pin.
Figure 6-86. ETPUA[16]_PCSD[1]_GPIO[130] Pad Configuration Register (SIU_PCR130)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.75 Pad Configuration Register 131 (SIU_PCR131)
The SIU_PCR131 register controls the pin function, direction, and static electrical attributes of the
ETPUA[17]_PCSD[2]_GPIO[131] pin.

When configured as PCS, the OBE bit has no effect. The OBE bit must be set to 1 for both ETPUA or 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.
