This register is used to specify the sampling clock and resolution (number of samplings) of the analog input to
be A/D converted.
This register is used to specify the analog input pin to be A/D converted.
This register is used to specify the buffer mode and operation mode of the A/D conversion.
This register is used to check the A/D-converted analog input pin.
The controller selects the analog input pin, generates the operation timing of the first-order ΔΣ modulator and
digital filter, and controls the conversion trigger according to the mode set by the ADA2CTL0, ADA2CTL1,
ADA2CTL2, and ADA2CTL3 registers.
The ANI2n pin is an analog input pin for A/D converter 2 (V850E/IA3: n = 0 to 5, V850E/IA4: n = 0 to 7). These
pins input the analog signals to be A/D converted.
Caution Make sure that the voltages input to ANI2n do not exceed the rated values. If a voltage
