6.3.1.105 Pad Configuration Register 194 (SIU_PCR194)
The SIU_PCR194 register controls the function, direction, and electrical attributes of
EMIOS[15]_IRQ[1]_CNRXD_GPIO[194]. Both input and output functions of EMIOS[15] are connected.
Figure 6-106. EMIOS[15]_IRQ[1]_CNRXD_GPIO[194] Pad Configuration Register (SIU_PCR194)
Refer to Table 6-19 for bit field definitions. Table 6-105 lists the PA fields for
EMIOS[15]_IRQ[1]_CNRXD_GPIO[194].
6.3.1.106 Pad Configuration Register 195 (SIU_PCR195)
The SIU_PCR195 register controls the function, direction, and electrical attributes of
EMIOS[16]_ETPUB[0]_GPIO[195]. Both the input and output functions of EMIOS[16] are connected.
Only the output channel of ETPUB[0] is 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 CNRXD or GPIO[194] when configured as input.

The weak pullup/down selection at reset for the EMIOS[15] pin is determined by the WKPCFG pin.
