3.2 External Signal Description
This section lists and describes the signals that connect off chip.
Table 3-1 shows all the pins and their functions that are controlled by the PIM9E128V1. The order in
which the pin functions are listed represents the functions priority (top – highest priority, bottom – lowest
priority).
