System pins
Table 4 and Table 5 contain information on pin functions for the MPC5602P devices. The pins listed in Table 4 are
single-function pins. The pins shown in Table 5 are multi-function pins, programmable via their respective pad configuration
register (PCR) values.
2.2.3
Pin multiplexing
Table 5 defines the pin list and muxing for the MPC5602P devices.
Each row of Table 5 shows all the possible ways of configuring each pin, via alternate functions. The default function assigned
to each pin after reset is the ALT0 function.
MPC5602P devices provide three main I/O pad types, depending on the associated functions:
Slow pads are the most common, providing a compromise between transition time and low electromagnetic emission.
Medium pads provide fast enough transition for serial communication channels with controlled current to reduce
electromagnetic emission.
Fast pads provide maximum speed. They are used for improved NEXUS debugging capability.
Medium and Fast pads can use slow configuration to reduce electromagnetic emission, at the cost of reducing AC performance.
For more information, see “Pad AC Specifications” in the device data sheet.
