6.3.1.12.90 Pad Configuration Register 179–188 (SIU_PCR179–SIU_PCR188)
The SIU_PCR179–SIU_PCR188 registers control the pin function, direction, and static electrical
attributes of the EMIOS[0:9]_ETPUA[0:9]_GPIO[179:188] pins. The input and output functions for
EMIOS[0:9] are connected to pins; ETPUA[0:9] are connected to output channel pins only.

Refer to Table 6-16 for bit field definitions.
6.3.1.12.91 Pad Configuration Register 189–190 (SIU_PCR189–SIU_PCR190)
The SIU_PCR189–SIU_PCR190 registers control the pin function, direction, and static electrical
attributes of the EMIOS[10:11]_GPIO[189:190] pins. Both the input and output functions of
EMIOS[10:11] are connected to pins.

When configured as EMIOS, 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 EMIOS[0:9] or GPIO[179:188] when configured as inputs.

When configured as EMIOS 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 both EMIOS[10:11] and GPIO[189:190] when
configured as inputs.
