Description
Ground reference for logic and I/O pins.
Positive supply for most of the logic function,
including the processor core and most
peripherals.
GPIO port B bit 7
JTAG TRSTn
GPIO port B bit 6
Analog comparator 0 positive input
Analog comparator 0 output
GPIO port B bit 5
Analog comparator 1 negative input
GPIO port B bit 4
Analog comparator 0 negative input
Positive supply for I/O and some logic.
Ground reference for logic and I/O pins.
GPIO port D bit 4
Capture/Compare/PWM 0
GPIO port D bit 5
Capture/Compare/PWM 2
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.
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.
GPIO port D bit 6
PWM Fault
GPIO port D bit 7
QEI module 0 index
