(5) Serial resistor string
The serial resistor string is configured between AV
REF
and AV
SS
. It generates the reference voltages against
which analog inputs are compared.
(6) ANI0 to ANI6 pins
Pins ANI0 to ANI6 are analog input pins for the A/D converter. They are used to receive the analog signals
to be subject to A/D conversion.
Caution
Do not supply pins ANI0 to ANI6 with voltages that fall outside the rated range. If a
voltage greater than AV
REF
or less than AV
SS
(even if within the absolute maximum
rating) is supplied to any of these pins, the conversion value for the corresponding
channel will be undefined. Furthermore, the conversion values for the other channels
may also be affected.
(7) AV
REF
pin
The AV
REF
pin is a reference voltage pin for the A/D converter.
Signals received at pins ANI0 to ANI6 are converted to digital signals while referencing the voltage across the
AV
REF
and AV
SS
pins.
(8) AV
SS
pin
The AV
SS
pin is a ground potential pin for the A/D converter. This pin must be held at the same potential as
the V
SS0
pin, even while the A/D converter is not being used.
(9) AV
DD
pin
The AV
DD
pin is an analog power supply pin for the A/D converter. This pin must be held at the same
potential as the V
DD0
pin, even while the A/D converter is not being used.
