6.3.1.102 Pad Configuration Register 198 (SIU_PCR198)
The SIU_PCR198 register controls the function, direction, and electrical attributes of the
EMIOS[19]_GPIO[198] pin. Both the input and output functions of EMIOS[19] are connected.
Figure 6-100. EMIOS[19]_GPIO[198] Pad Configuration Register (SIU_PCR198)
Refer to Table 6-19 for bit field definitions. Table 6-95 lists the PA fields for EMIOS[19]_GPIO[198].
6.3.1.103 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]_GPIO[199:200]. Both the input and output functions of EMIOS[20:21] are connected.

The OBE bit must be set to 1 for EMIOS[19] and GPIO[198] 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[19] or GPIO[198] when configured as input.
