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 func-
tions, this is noted under the the first table where this apply.
