6.3.1.12.22 MPC5554: Pad Configuration Registers 60–61 (SIU_PCR60–SIU_PCR61)
NOTE
The MPC5553 does not implement PCRs 60–61; therefore, these registers
are reserved on the MPC5553.
The SIU_PCR60–SIU_PCR61 registers control the pin function, direction, and static electrical attributes
of the TSIZ[0:1]_GPIO[60:61] pins.

Refer to Table 6-16 for bit field definitions.
6.3.1.12.23 Pad Configuration Register 62 (SIU_PCR62)
The SIU_PCR62 register controls the pin function, direction, and static electrical attributes of the
RD_WR_GPIO[62] pin. Because the MPC5553 calibration bus interface (CBI) and external bus interface
(EBI) share the same physical bus, the MPC5553 uses the RD_WR signal for the CBI as well as the EBI.

When configured as TSIZ[0:1], the OBE bit has no effect. When configured as GPO, set the OBE bit to 1.
IBE

When configured as TSIZ[0:1] 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.
