Description
Analog Inputs. The A/D converter cell can measure the voltage on any of these input signals.
Note that these analog inputs are always connected to their pins, even if the Pin Multiplexing
Register assigns them to port pins. A simple self-test of the A/D Converter can be done by driving
these pins as port outputs.
Note: while the ADC pins are specified as 5 V tolerant (see
in the ADC block is not. More than V
that is selected as an ADC input, or the ADC reading will be incorrect. If for example AD0.0 and
AD0.1 are used as the ADC0 inputs and voltage on AD0.0 = 4.5 V while AD0.1 = 2.5 V, an
excessive voltage on the AD0.0 can cause an incorrect reading of the AD0.1, although the AD0.1
input voltage is within the right range.
If the A/D converter is not used in an application then the pins associated with A/D inputs can be
used as 5V tolerant digital IO pins
Analog Power and Ground. These should be nominally the same voltages as V
respectively but should be isolated to minimize noise and error.

A/D Global Data Register. Contains the result
of the most recent A/D conversion.
A/D Status Register. This register contains
DONE and OVERRUN flags for all of the A/D
channels, as well as the A/D interrupt flag.
contains enable bits that allow the DONE flag
of each A/D channel to be included or
excluded from contributing to the generation
of an A/D interrupt.
