28.1.5 Communication functions

28.1.6 Oscillators, Clock and Event

28.1.7 Debug/System functions

28.2 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.
