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.
