7.4 Analog Port (APORT) Client Maps
The Analog Port (APORT) is an infrastructure used to connect chip pins with on-chip analog clients such as analog comparators, ADCs,
DACs, etc. The APORT consists of a set of shared buses, switches, and control logic needed to configurably implement the signal rout-
ing.
Figure 7.2 APORT Connection Diagram on page 101
shows the APORT routing for this device family (note that available features
may vary by part number). A complete description of APORT functionality can be found in the Reference Manual.

Figure 7.2. APORT Connection Diagram
Client maps for each analog circuit using the APORT are shown in the following tables. The maps are organized by bus, and show the
peripheral's port connection, the shared bus, and the connection from specific bus channel numbers to GPIO pins.
