MPC5554: Pad Configuration Register 165 (SIU_PCR165)
NOTE
The MPC5553 does not implement PCR165. This register is reserved in the
MPC5553.
The SIU_PCR165 register controls the pin function, direction, and static electrical attributes of the
ETPUB[18]_PCSA[3]_GPIO[165] pin. Both the input and output channel of ETPUB[18] are connected
to the pin.

6.3.1.12.88
Pad Configuration Register 166 (SIU_PCR166)
NOTE
The MPC5553 does not implement PCR166. This register is reserved in the
MPC5553.
The SIU_PCR166 register controls the pin function, direction, and static electrical attributes of the
ETPUB[19]_PCSA[4]_GPIO[166] pin. Both the input and output channel of ETPUB[19] are connected
to the pin.

The OBE bit must be set to 1 for ETPUB[18] or GPIO[165] 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[18] or
GPIO[165] when configured as inputs.
