Signal Tables
The following tables list the signals available for each pin. Functionality is enabled by software with
the GPIOAFSEL register (see page 123).
Important:
signals in alphabetical order by signal name. groups the signals by functionality, except for
GPIOs. lists the GPIO pins and their alternate functionality.
shows the pin-to-signal-name mapping, including functional characteristics of the signals. lists the

Pin Name
All multiplexed pins are GPIOs by default, with the exception of the five JTAG pins
(PB7 and PC[3:0]) which default to the JTAG functionality.
