Buffer Type Description
TTL
VCC of the Ethernet PHY
Analog RXIN of the Ethernet PHY
Power
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Power Ground reference for logic and I/O pins.
Analog RXIP of the Ethernet PHY
TTL
GND of the Ethernet PHY
TTL
GND of Ethernet PHY
Analog TXOP of Ethernet PHY
Power Positive supply for I/O and some logic.
Power Ground reference for logic and I/O pins.
Analog TXON of Ethernet PHY
TTL
GPIO port F bit 0
Analog
Main oscillator crystal input or an external
clock reference input.
Analog Main oscillator crystal output.
OD
An external input that brings the processor out
of hibernate mode when asserted.
TTL
An output that indicates the processor is in
hibernate mode.
Analog
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.
Analog Hibernation Module oscillator crystal output.
Power Ground reference for logic and I/O pins.
Power
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.
Power Positive supply for I/O and some logic.
Power Ground reference for logic and I/O pins.
TTL
