Signal Properties

Table 24-1 shows all the pins and their functions that are controlled by the PIM. Refer to Section ,

“Functional Description” for the availability of the individual pins in the different package options.

NOTE

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 bottom

(lowest priority).
