Refer to Table 6-16 for bit field definitions. Table 6-40 lists the PA field values for the MPC5553 PCR73.
6.3.1.12.36 MPC5554: Pad Configuration Register 73 (SIU_PCR73)
The SIU_PCR73 register controls the pin function, direction, and static electrical attributes of the
BG_GPIO[73] pin.

Refer to Table 6-16 for bit field definitions.
6.3.1.12.37 MPC5554: Pad Configuration Register 74 (SIU_PCR74)
NOTE
The MPC5553 does not implement PCR74, therefore this register is
reserved on the MPC5553.
The SIU_PCR74 register controls the pin function, direction, and static electrical attributes of the
BB_GPIO[74] pin.

1
When configured as BG, the OBE bit has no effect. When configured as GPO, set the OBE bit to 1.
IBE
2
2
When configured as BG or GPO, set the IBE bit to 1 to reflect the pin state in the corresponding GPDI register. Clearing the IBE
bit to 0 reduces power consumption. When configured as GPI, set the IBE bit to 1.
DSC ODE

3
When configured as BG, and external master operation is enabled with internal arbitration, clear the ODE bit to 0.

If external master operation is enabled, clear the HYS bit to 0.
