Signal Tables
The following tables list the signals available for each pin. Functionality is enabled by software with
the GPIOAFSEL register (see page 109).
Important:
Table 15-1 shows the pin-to-signal-name mapping, including functional characteristics of the
signals. Table 15-2 lists the signals in alphabetical order by signal name. Table 15-3 groups the
signals by functionality. Table 15-4 lists the GPIO pins and their alternate functionality.
