Refer to Table 6-19 for bit field definitions. Table 6-84 lists the PA fields for
ETPUA[28:30]_PCSC[1:3]_GPIO[142:144].
6.3.1.91 Pad Configuration Register 145 (SIU_PCR145)
The SIU_PCR145 register controls the function, direction, and electrical attributes of
ETPUA[31]_PCSC[4]_GPIO[145].

Refer to Table 6-19 for bit field definitions. Table 6-85 lists the PA fields for
ETPUA[31]_PCSC[4]_GPIO[145].
6.3.1.92 Pad Configuration Registers 146–178 (SIU_PCR146–SIU_PCR178)
The SIU_PCR146–SIU_PCR178 registers are not implemented in this device.

When configured as PCSC[4], the OBE bit has no effect. When configured as ETPUA[31] output or GPDO, set the OBE bit 1.

When the pad is configured as an output, set the IBE bit to 1 show the pin state in the corresponding GPDI register. Clear the
IBE bit to 0 reduces power consumption. Set the IBE bit to 1 for ETPUA or GPIO when configured as input.
