(6) ANI0 to ANI11 pins
(7) AV
(8) AV
(9) AV
These are analog input pins for the 12 channels of the A/D converter, and are used to input analog signals to be
converted into digital signals. Pins other than ones selected as the analog input by the analog input channel
specification register (ADS) can be used as input ports.
This pin inputs a reference voltage to the A/D converter.
The signals input to the ANI0 through ANI11 pins are converted into digital signals based on the voltage applied
across AV
This is the ground pin of the A/D converter. Always keep the potential at this pin the same as that at the V
even when the A/D converter is not in use.
This is the analog power supply pin of the A/D converter. Always keep the potential at this pin the same as that at

Caution Make sure that the voltages input to ANI0 through ANI11 do not exceed the rated values. If a
