Signal Tables
The following tables list the signals available for each pin. Functionality is enabled by software with
the GPIOAFSEL register.
Important:
Table 16-1 on page 342 shows the pin-to-signal-name mapping, including functional characteristics
of the signals. Table 16-2 on page 344 lists the signals in alphabetical order by signal name.
Table 16-3 on page 346 groups the signals by functionality, except for GPIOs. Table 16-4 on page
347 lists the GPIO pins and their alternate functionality.

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.
