Note:
1 _{Only on Rev C.2 silicon.}
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 _{Must be pulled down or left floating.}
4 _{Must be pulled down or left floating. However, if compatibility with HiP4 silicon is required, this pin must be pulled up or left}
floating.
5 _{For information on how to use this pin, refer to MPC8260 PowerQUICC II Thermal Resistor Guide available at}
