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.
