4.2 Alternate Functionality Pinout
A wide selection of alternate functionality is available for multiplexing to various pins. This is shown in
Table 4.2 (p. 50) . 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 LOCA-
TION bitfield. In these cases, the pinout is shown in the column corresponding to LOCA-
TION 0.
