Chapter 2 Port Integration Module (PIM9C32) Block Description
76 MC9S12C-Family / MC9S12GC-Family Freescale Semiconductor
Rev 01.24
2.2 Signal Description
This section lists and describes the signals that do connect off-chip.
Table 2-1 shows all pins and their functions that are controlled by the PIM module. If there is more than
one function associated to a pin, the priority is indicated by the position in the table from top (highest
priority) to down (lowest priority).
