Description
GPIO port C bit 1
JTAG TMS and SWDIO
JTAG TMS and SWDIO
CPU Mode bit 1. Input must be set to logic 0
(grounded); other encodings reserved.
GPIO port E bit 2
SSI module 1 receive
GPIO port E bit 1
SSI module 1 frame
No connect. Leave the pin electrically
unconnected/isolated.
No connect. Leave the pin electrically
unconnected/isolated.
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Ground reference for logic and I/O pins.
Ground reference for logic and I/O pins.
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.
