-
Power The positive supply for the analog circuits (ADC, Analog
98
Comparators, etc.). These are separated from VDD to
minimize the electrical noise contained on VDD from affecting
the analog functions. VDDA pins must be supplied with a
voltage that meets the specification in “Recommended DC
Operating Conditions” on page 541, regardless of system
implementation.
WAKE

I
TTL
An external input that brings the processor out of Hibernate
mode when asserted.
XOSC0
52
I
Analog 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.
XOSC1
53
O
Analog Hibernation module oscillator crystal output. Leave
unconnected when using a single-ended clock source.
a. The TTL designation indicates the pin has TTL-compatible voltage levels.
