Refer to Table 6-19 for bit field definitions. Table 6-90 lists the PA fields for
EMIOS[14]_IRQ[0]_GPIO[193].
6.3.1.98 Pad Configuration Register 194 (SIU_PCR194)
The SIU_PCR194 register controls the function, direction, and electrical attributes of
EMIOS[15]_IRQ[1]_GPIO[194]. Both input and output functions of EMIOS[15] are connected.

Refer to Table 6-19 for bit field definitions. Table 6-91 lists the PA fields for
EMIOS[15]_IRQ[1]_GPIO[194].

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 one for GPIO[194] when configured as input.
