6.3.1.12.92 Pad Configuration Register 191 (SIU_PCR191)
The SIU_PCR191 register controls the pin function, direction, and static electrical attributes of the
EMIOS[12]_SOUTC_GPIO[191] pin. Only the output of EMIOS[12] is connected to the pin.
Figure 6-104. EMIOS[12]_SOUTC_GPIO[191] Pad Configuration Register (SIU_PCR191)
Refer to Table 6-16 for bit field definitions.
6.3.1.12.93 Pad Configuration Register 192 (SIU_PCR192)
The SIU_PCR192 register controls the pin function, direction, and static electrical attributes of the
EMIOS[13]_SOUTD_GPIO[192] pin. Only the output of EMIOS[13] is connected to the pin.

When configured as EMIOS or GPO, set the IBE bit to 1 to reflect the pin state in the corresponding GPDI register. Clear the
IBE to 0 to reduce power consumption. The IBE bit must be set to 1 for GPIO[191] when configured as an input.
