6.3.1.12.29 Pad Configuration Register 69 (SIU_PCR69)
The SIU_PCR69 register controls the pin function, direction, and static electrical attributes of the
TS_GPIO[69] pin. Because the MPC5553 calibration bus interface (CBI) and external bus interface (EBI)
share the same physical bus, the MPC5553 uses the TS signal for the CBI as well as the EBI.

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

2
When configured as OE 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.
