Description
Used in Host mode by an external power
source to indicate an error state by that power
source.
9.1 KOhm resistor (1% precision) used
internally for USB analog circuitry.
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.
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.
Positive supply for I/O and some logic.
Positive supply for I/O and some logic.
Positive supply for I/O and some logic.
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Positive supply for most of the logic function,
including the processor core and most
peripherals.
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.
An external input that brings the processor out
of hibernate mode when asserted.
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.
