13.3 Control Registers
(5) D/A converter
(6) ANI2n pin
(7) AV
(8) AV
A/D converter 2 is controlled by the following registers.
• A/D converter 2 mode registers 0, 1 (AD2M0 to AD2M1)
• A/D converter 2 channel specification register (AD2S)
The following registers are also used.
• A/D2 conversion result register n (AD2CRn)
• A/D2 conversion result register nH (AD2CRnH)
The D/A converter is connected between AV
input analog signal.
The ANI2n pin is an analog input pin for A/D converter 2. This pin inputs the analog signals to be A/D
converted. Pins other than the one that is selected by the AD2S register as analog signal input pins can be
used as input port pins.
Cautions 1. Make sure that the voltages input to the ANI2n pin do not exceed the rated values. If a

2. The analog input pin (ANI2n) is alternately used as input port pin (P7n). If an instruction
pin alternately functions as the pin for inputting the positive power supply and reference voltage of
voltage higher than or equal to AV
the conversion value of the channel is undefined, and the conversion values of the other
channels may also be affected.

for A/D conversion, the resolution for conversion may drop.
