5.4.2 Alternate Functionality Pinout
A wide selection of alternate functionality is available for multiplexing to various pins. This is shown in the following 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 not have alternate settings or a LOCATION bitfield. In these cases, the pinout
is shown in the column corresponding to LOCATION 0.
