6.3.1.12.80 Pad Configuration Register 143 (SIU_PCR143)
The SIU_PCR143 register controls the pin function, direction, and static electrical attributes of the
ETPUA[29]_PCSC[2]_GPIO[143] pin. Only the output channel of ETPUA[29] is connected to the pin.
Figure 6-92. ETPUA[29]_PCSC[2]_GPIO[143] Pad Configuration Register (SIU_PCR143)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.81 Pad Configuration Register 144 (SIU_PCR144)
The SIU_PCR144 register controls the pin function, direction, and static electrical attributes of the
ETPUA[30]_PCSC[3]_GPIO[144] pin.

When configured as ETPUA or PCS, the OBE bit has no effect. When configured as GPO, set the OBE bit to 1.

When configured as ETPUA, PCS, or GPO, set the IBE bit to 1 to reflect the pin state in the corresponding GPDI register. Clear
the IBE to 0 to reduce power consumption. The IBE bit must be set to 1 for GPIO when configured as input.
