Chapter 4 Port Integration Module (PIM9KG128V1)
4.2 External Signal Description
This section lists and describes the signals that do connect off chip.
4.2.1 Signal Properties
Table 4-1 shows all the pins and their functions that are controlled by the PIM9KG128. If there is more
than one function associated with a pin, the priority is indicated by the position in the table from top
(highest priority) to down (lowest priority). All pins have reset state as input.
