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
This signal senses the state of the USB ID
signal. The USB PHY enables an integrated
pull-up, and an external element (USB
connector) indicates the initial state of the USB
controller (pulled down is an A device and not
pulled down is a B device).
GPIO port B bit 1
This signal is used during the session
negotiation protocol. This signal allows the
USB PHY to both sense the voltage level of
VBUS, and pull up VBUS momentarily during
VBUS pulsing.
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.
