System Pins
Table 3 and
Table 4 contain information on pin functions for the MPC560xP devices. The pins listed in
Table 3 are
single-function pins. The pins shown in
Table 4 are multi-function pins, programmable via their respective Pad Configuration
Register (PCR) values.
VSS_LV_COR0
1.2 V Decoupling pins for core logic. Decoupling
capacitor must be connected between these pins and
the nearest VDD_LV_COR pin.
