6.3.1.12.50 Pad Configuration Register 94 (SIU_PCR94)
The SIU_PCR94 register controls the pin function, direction, and static electrical attributes of the
SINA_PCSC[2]_GPIO[94] pin. The SINA function is only available on the MPC5554. Although the
SINA function is not available in the MPC5553, this register enables the selection of the PCSC[2] or GPIO
function for the MPC5553.

Refer to Table 6-16 for bit field definitions.
6.3.1.12.51 Pad Configuration Register 95 (SIU_PCR95)
The SIU_PCR95 register controls the pin function, direction, and static electrical attributes of the
SOUTA_PCSC[5]_GPIO[95] pin. The SOUTA function is only available on the MPC5554. Although the
SOUTA function is not available in the MPC5553, this register enables the selection of the PCSC[5] or
GPIO function for the MPC5553.

The SINA function is only available on the MPC5554; it is not available on the MPC5553. Therefore, set the PA field value for
0b01 or 0b11 only on the MPC5554. Valid MPC5553 PA settings are 0b10 for the PCSC[2] or 0b00 for GPIO.

When configured as SINA or PCS, the OBE bit has no effect. When configured as GPO, set the OBE bit to 1.
IBE

When configured as SINA, PCS, 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. When configured as GPI, set the IBE bit to 1.
