Pin muxing
Table 5 defines the pin list and muxing for the MPC5604P 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.
MPC5604P devices provide four 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.
Symmetric pads are designed to meet FlexRay requirements.
Medium and Fast pads can use slow configuration to reduce electromagnetic emission, at the cost of reducing AC performance.
For more information, see the data sheet’s “Pad AC Specifications” section.
