Description
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 most of the logic function,
including the processor core and most
peripherals.
Ground reference for logic and I/O pins.
System reset input.
GPIO port B bit 0
UART 1 receive
GPIO port B bit 1
UART 1 transmit
Positive supply for I/O and some logic.
Ground reference for logic and I/O pins.
Bidirectional differential data pin (D- per USB
specification).
Bidirectional differential data pin (D+ per USB
specification).
GPIO port B bit 2
I2C module 0 clock
9.1 KOhm resistor (1% precision) used
internally for USB analog circuitry.
