6.3.1.108 Pad Configuration Register 197 (SIU_PCR197)
The SIU_PCR197 register controls the function, direction, and electrical attributes of
EMIOS[18]_ETPUB[2]_GPIO[197]. Both the input and output functions of EMIOS[18] is connected.
Only the output channels of ETPUB[2] is connected.
Figure 6-109. EMIOS[18]_ETPUB[2]_GPIO[197] Pad Configuration Register (SIU_PCR197)
Refer to Table 6-19 for bit field definitions. Table 6-108 lists the PA fields for
EMIOS[18]_ETPUB[2]_GPIO[197].
6.3.1.109 Pad Configuration Register 198 (SIU_PCR198)
The SIU_PCR198 register controls the function, direction, and electrical attributes of the
EMIOS[19]_ETPUB[3]_GPIO[198] pin. Both the input and output functions of EMIOS[19] are
connected. Only the output channels of ETPUB[3] are connected.

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.
