1 Should be tied to VDDH via a 2K Ω external pull-up resistor.
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 If PCI is not desired, must be pulled up or left floating.
5 Sphere is not connected to die.
6 GNDSYN (AB1): This pin exists as a separate ground signal in MPC826x(A) devices; it does not exist as a separate ground
signal on the SoC. New designs must connect AB1 to GND and follow the suggestions in Section 4.6, “Layout Practices.” Old
designs in which the MPC8280 is used as a drop-in replacement can leave the pin connected to GND with the noise filtering
capacitors.
7 XFC (AB2) pin: This pin is used in MPC826x(A) devices; it is not used in MPC8280 because there is no need for external
capacitor to operate the PLL. New designs should connect AB2 (XFC) pin to GND. Old designs in which the SoC is used as a
drop-in replacement can leave the pin connected to the current capacitor.

Symbol
Meaning
OVERBAR
Signals with overbars, such as TA, are active low.
UTM
Indicates that a signal is part of the UTOPIA master interface.
UTS
Indicates that a signal is part of the UTOPIA slave interface.
UT8
Indicates that a signal is part of the 8-bit UTOPIA interface.
UT16
Indicates that a signal is part of the 16-bit UTOPIA interface.
MII
Indicates that a signal is part of the media independent interface.
RMII
Indicates that a signal is part of the reduced media independent interface.
