Description
12.4 KOhm resistor (1% precision) used
internally for Ethernet PHY.
GND of the Ethernet PHY
TXOP of the Ethernet PHY
Positive supply for I/O and some logic.
Ground reference for logic and I/O pins.
TXON of the Ethernet PHY
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.
MDIO of the Ethernet PHY
GPIO port F bit 3
MII LED 0
GPIO port F bit 2
MII LED 1
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.
System reset input.
CPU Mode bit 0. Input must be set to logic 0
(grounded); other encodings reserved.
GPIO port B bit 0
Capture/Compare/PWM 0
GPIO port B bit 1
