6.5 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. A complete description of APORT functionality can be found in the Reference Manual.
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.
In general, enumerations for the pin selection field in an analog peripheral's register can be determined by finding the desired pin con-
nection in the table and then combining the value in the Port column (APORT__), and the channel identifier (CH__). For example, if pin
PF7 is available on port APORT2X as CH23, the register field enumeration to connect to PF7 would be APORT2XCH23. The shared
bus used by this connection is indicated in the Bus column.
