Signal Tables
The following tables list the signals available for each pin. Functionality is enabled by software with
the GPIOAFSEL register (see page 125).
Important:
Table 18-1 shows the pin-to-signal-name mapping, including functional characteristics of the
signals. Table 18-2 lists the signals in alphabetical order by signal name. Table 18-3 groups the
signals by functionality, except for GPIOs. Table 18-4 lists the GPIO pins and their alternate
functionality.

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.
