-
Power Positive supply for most of the logic function, including the

VDDA
3
-
Power 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. VDDA pins must be connected
to 3.3 V, regardless of system implementation.
WAKE
32
I
TTL
An external input that brings the processor out of Hibernate
mode when asserted.
XOSC0
34
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
35
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.
