Description
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.
No connect. Leave the pin electrically
unconnected/isolated.
No connect. Leave the pin electrically
unconnected/isolated.
No connect. Leave the pin electrically
unconnected/isolated.
No connect. Leave the pin electrically
unconnected/isolated.
Positive supply for I/O and some logic.
Ground reference for logic and I/O pins.
No connect. Leave the pin electrically
unconnected/isolated.
GPIO port F bit 0
Main oscillator crystal input or an external
clock reference input.
Main oscillator crystal output.
An external input that brings the processor out
of hibernate mode when asserted.
An output that indicates the processor is in
hibernate mode.
Hibernation Module oscillator crystal input or
an external clock reference input. Note that
this is either a 4.19-MHz crystal or a
32.768-kHz oscillator for the Hibernation
Module RTC. See the CLKSEL bit in the
HIBCTL register.
Hibernation Module oscillator crystal output.
Ground reference for logic and I/O pins.
Power source for the Hibernation Module. It
is normally connected to the positive terminal
of a battery and serves as the battery
backup/Hibernation Module power-source
supply.
Positive supply for I/O and some logic.
Ground reference for logic and I/O pins.
No connect. Leave the pin electrically
unconnected/isolated.
GPIO port F bit 3
GPIO port F bit 2
GPIO port F bit 1
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Ground reference for logic and I/O pins.
