CHAPTER 11 A/D CONVERTER
11.1 Function
The A/D converter converts analog input signals into digital values with a resolution of 10 bits, and can handle 12
channels of analog input signals (ANI0 to ANI11).
The V850/SB1 and V850/SB2 support the low power consumption mode by low-speed conversion.
(1) Hardware start
Conversion is started by trigger input (ADTRG) (rising edge, falling edge, or both rising and falling edges can be
specified).
(2) Software start
Conversion is started by setting A/D converter mode register 1 (ADM1).
One analog input channel is selected from ANI0 to ANI11, and A/D conversion is performed. If A/D conversion
has been started by means of a hardware start, conversion stops once it has been completed, and an interrupt
request (INTAD) is generated. If conversion has been started by means of a software start, conversion is performed
repeatedly. Each time conversion is completed, INTAD is generated.
