Refer to Table 6-19 for bit field definitions. Table 6-100 lists the PA fields for
EMIOS[0:9]_ETPUA[0:9]_GPIO[179:188].
6.3.1.101 Pad Configuration Register 189–190 (SIU_PCR189–SIU_PCR190)
The SIU_PCR189–SIU_PCR190 registers control the function, direction, and electrical attributes of
EMIOS[10:11]_PCSD[3:4]_GPIO[189:190]. Both the input and output functions of EMIOS[10:11] are
connected.

Refer to Table 6-19 for bit field definitions. Table 6-101 lists the PA fields for
EMIOS[10:11]_PCSD[3:4]_GPIO[189:190].

When the pad is configured as an output, set the IBE bit to 1 to show the pin state in the GPDI register. Clear the IBE bit to 0
to reduce power consumption. The IBE bit must be set to 1 for EMIOS[10:11] or GPIO[189:190] when configured as input.
