6.3.1.12.86 MPC5554: Pad Configuration Register 164 (SIU_PCR164)
NOTE
The MPC5553 does not implement PCR164. This register is reserved in the
MPC5553.
The SIU_PCR164 register controls the pin function, direction, and static electrical attributes of the
ETPUB[17]_PCSA[2]_GPIO[164] pin. Both the input and output channel of ETPUB[17] are connected
to the pin.

The OBE bit must be set to 1 for both ETPUB and GPIO 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 both ETPUB
and GPIO when configured as inputs.
