Pin muxing

Table 7 defines the pin list and muxing for the SPC56xP54/60 devices relative to Full-

featured version.

Each row of Table 7 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.

Pins marked as external interrupt capable can also be used to resume from STOP and

HALT mode.

SPC56xP54/60 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.
