Refer to Table 6-19 for bit field definitions. Table 6-109 lists the PA fields for
EMIOS[19]_ETPUB[3]_GPIO[198].
6.3.1.110 Pad Configuration Registers 199–200 (SIU_PCR199–SIU_PCR200)
The SIU_PCR199–SIU_PCR200 registers control the function, direction, and electrical attributes of
EMIOS[20:21]_ETPUB[4:5]_GPIO[199:200]. Both the input and output functions of EMIOS[20:21] are
connected. Only the output channels of ETPUB[4:5] are connected.

The OBE bit must be set to 1 for EMIOS[20:21] or GPIO[199:200] when configured as output.

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[20:21] or GPIO[199:200] when configured as input.

The weak pullup/down selection at reset for the EMIOS[20:21] pin is determined by the WKPCFG pin.
