Signal Tables
The following tables list the signals available for each pin. Functionality is enabled by software with
the GPIOAFSEL register.
Important:
Table 18-1 on page 437 shows the pin-to-signal-name mapping, including functional characteristics
of the signals. Table 18-2 on page 441 lists the signals in alphabetical order by signal name.
Table 18-3 on page 444 groups the signals by functionality, except for GPIOs. Table 18-4 on page
447 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.

Description
No connect
No connect
The positive supply (3.3 V) for the analog
circuits (ADC, Analog Comparators, etc.).
These are separated from VDD to minimize
the electrical noise contained on VDD from
affecting the analog functions.
The ground reference for the analog circuits
(ADC, Analog Comparators, etc.). These are
separated from GND to minimize the electrical
noise contained on VDD from affecting the
analog functions.
No connect
No connect
Low drop-out regulator output voltage. This
pin requires an external capacitor between
the pin and GND of 1 µF or greater. When the
on-chip LDO is used to provide power to the
logic, the LDO pin must also be connected to
the VDD25 pins at the board level in addition
to the decoupling capacitor(s).
Positive supply for I/O and some logic.
Ground reference for logic and I/O pins.
GPIO port D bit 0
CAN module 0 receive
GPIO port D bit 1
CAN module 0 transmit
GPIO port D bit 2
GPIO port D bit 3
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Ground reference for logic and I/O pins.
