External Signal Description
3.2 External Signal Description
This section lists and describes the signals that connect off-chip.
Table 3-1 shows all pins and their functions that are controlled by the PIM_9NE64 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 bottom (lowest priority).
