6.5 Alternate Functionality Overview
A wide selection of alternate functionality is available for multiplexing to various pins. The following table shows the name of the alter-
nate functionality in the first column, followed by columns showing the possible LOCATION bitfield settings and the associated GPIO
pin. Refer to 6.4 GPIO Functionality Table for a list of functions available on each GPIO pin.
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.
