I
Analog Hibernation module oscillator crystal input or an
external clock reference input. Note that this is
either a 4.194304-MHz crystal or a 32.768-kHz
oscillator for the Hibernation module RTC. See the
CLKSEL bit in the HIBCTL register.

O
Analog Hibernation module oscillator crystal output. Leave
unconnected when using a single-ended clock
source.

This input provides a reference voltage used to
specify the input voltage at which the ADC converts
to a maximum value. In other words, the voltage
that is applied to VREFA is the voltage with which
an AINn signal is converted to 4095. The VREFA
input is limited to the range specified in Table
21-26 on page 912 .
