Notes:

1. MPC8265 and MPC8266 only.

2. The default configuration of the CPM pins (PA[0–31], PB[4–31], PC[0–31], PD[4–31]) is input. To prevent excessive

DC current, it is recommended to either pull unused pins to GND or VDDH, or to configure them as outputs.

3. On PCI devices (MPC8265 and MPC8266) this pin should be used as CLKIN2. On non-PCI devices (MPC8260A

and MPC8264) this is a spare pin that must be pulled down or left floating.

4. Must be pulled down or left floating.

5. On PCI devices (MPC8265 and MPC8266) this pin should be asserted if the PCI function is desired or pulled up or

left floating if PCI is not desired. On non-PCI devices (MPC8260A and MPC8264) this is a spare pin that must be pulled

up or left floating.

6. For information on how to use this pin, refer to
