6.3.1.12.94 Pad Configuration Register 193–194 (SIU_PCR193–SIU_PCR194)
The SIU_PCR193–SIU_PCR194 registers control the pin function, direction, and static electrical
attributes of the EMIOS[14:15]_IRQ[0:1]_GPIO[193:194] pins. Only the output functions of
EMIOS[14:15] are connected to pins.

Refer to Table 6-16 for bit field definitions.
6.3.1.12.95 Pad Configuration Register 195–202 (SIU_PCR195–SIU_PCR202)
MPC5553: The SIU_PCR195 through SIU_PCR202 registers control the pin function, direction, and
static electrical attributes of the EMIOS[16:23]_ETPUB[0:7]_GPIO[195:202] pins. The input and output
functions of EMIOS[16:23] are connected to pins. The alternate functions, ETPUB[0:7], are not available
on the MPC5553.
MPC5554: The SIU_PCR195 through SIU_PCR202 registers control the pin function, direction, and
static electrical attributes of the EMIOS[16:23]_ETPUB[0:7]_GPIO[195:202] pins. Both the input and
output functions of EMIOS[16:23] are connected to pins, however ETPUB[0:7] are connected only as
output channels to the pins.

When configured as EMIOS or IRQ 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[193:194] when configured as inputs.
