6.3.1.12.89 MPC5554: Pad Configuration Register 167–178 (SIU_PCR167–SIU_PCR178)
NOTE
The MPC5553 does not implement PCR167–178. These registers are
reserved in the MPC5553.
The SIU_PCR167–SIU_PCR178 registers control the pin function, direction, and static electrical
attributes of the ETPUB[20:31]_GPIO[167:178] pins. Both the inputs and outputs of ETPUB[20:31] are
connected to these pins.

The OBE bit must be set to 1 for ETPUB[19] or GPIO[166] when configured as outputs. When configured as PCS, the OBE bit
has no effect.

When configured as ETPUB or GPIO outputs, or configured as PCS, 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 ETPUB[19] or
GPIO[166] when configured as inputs.

The weak pullup/down selection at reset for the ETPUB[19] pin is determined by the WKPCFG pin.
