Refer to Table 6-19 for bit field definitions. Table 6-93 lists the PA fields for EMIOS[17]_GPIO[196].
6.3.1.101 Pad Configuration Register 197 (SIU_PCR197)
The SIU_PCR197 register controls the function, direction, and electrical attributes of
EMIOS[18]_GPIO[197]. Both the input and output functions of EMIOS[18] is connected.

The OBE bit must be set to 1 for EMIOS[18] or GPIO[197] when configured as output.
IBE

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[18] or GPIO[197] when configured as input.
