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 489 shows the pin-to-signal-name mapping, including functional characteristics
of the signals. Table 18-2 on page 492 lists the signals in alphabetical order by signal name.
Table 18-3 on page 495 groups the signals by functionality, except for GPIOs. Table 18-4 on page
497 lists the GPIO pins and their alternate functionality.

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

Description
GPIO port E bit 3
ADC 0 input
GPIO port E bit 2
ADC 1 input
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.
GPIO port E bit 1
ADC 2 input
GPIO port E bit 0
ADC 3 input
Low drop-out regulator output voltage. This
pin requires an external capacitor between
the pin and GND of 1 µF or greater. The LDO
pin must also be connected to the VDD25 pins
at the board level in addition to the decoupling
capacitor(s).
GPIO port E bit 4
UART2 transmit
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Ground reference for logic and I/O pins.
GPIO port C bit 4
Capture/Compare/PWM 2
Positive supply for I/O and some logic.
Ground reference for logic and I/O pins.
