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.

Must be pulled down or left floating.

If PCI is not desired, must be pulled up or left floating.

For information on how to use this pin, refer to

MPC8260 PowerQUICC II Thermal Resistor Guide (AN2271/D).
