Signal Tables
The following tables list the signals available for each pin. Functionality is enabled by software with
the GPIOAFSEL register.
Important:
Table 19-1 on page 423 shows the pin-to-signal-name mapping, including functional characteristics
of the signals. Table 19-2 on page 427 lists the signals in alphabetical order by signal name.
Table 19-3 on page 432 groups the signals by functionality, except for GPIOs. Table 19-4 on page
435 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
GPIO port E bit 7
PWM 5
GPIO port E bit 6
PWM 4
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 5
GPIO port E bit 4
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
PWM 0
GPIO port D bit 1
QEI module 0 Phase A
GPIO port D bit 2
UART module 1 receive. When in IrDA mode,
this signal has IrDA modulation.
GPIO port D bit 3
UART module 1 transmit. When in IrDA mode,
this signal has IrDA modulation.
