5.3 Alternate Functionality Pinout
A wide selection of alternate functionality is available for multiplexing to various pins. This is shown in the table. The table shows the
name of the alternate functionality in the first column, followed by columns showing the possible LOCATION bitfield settings.
Note: Some functionality, such as analog interfaces, do no have alternate settings or a LOCATION bitfield. In these cases, the pinout is
shown in the column corresponding to the LOCATION 0.
