VCCPHY
Ethernet PHY XTALN 25-MHz oscillator crystal
output. Connect this pin to ground when using a
single-ended 25-MHz clock input connected to the
XTALPPHY pin.

Ethernet PHY XTALP 25-MHz oscillator crystal
input or external clock reference input.

Capture/Compare/PWM 1.TTLI/O34CCP1
An open-drain output with internal pull-up that
indicates the processor is in Hibernate mode.
ODO51HIB
Hibernate
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-55VBAT
An external input that brings the processor out of
Hibernate mode when asserted.
TTLI50WAKE
Hibernation module oscillator crystal input or an
external clock reference input. Note that this is
either a crystal or a 32.768-kHz oscillator for the
Hibernation module RTC.
AnalogI52XOSC0
Hibernation module oscillator crystal output. Leave
unconnected when using a single-ended clock
source.
