I
Analog 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 1023. The VREFA input is limited
to the range specified in Table 21-26 on page 903 .
