29.2 Alternate Pin Functions
The tables below show the primary/default function for each pin on a port in the first column, the pin number in the
second column, and then all alternate pin functions in the remaining columns. The head row shows what peripheral that
enable and use the alternate pin functions.
For better flexibility, some alternate functions also have selectable pin locations for their functions, this is noted under the
first table where this apply.
Table 29-1. Port A - Alternate functions.
Table 29-2. Port B - Alternate functions.
Table 29-3. Port C - Alternate functions.
