A/D conversion
The operation mode of the A/D converter is the select mode. One channel of analog input is selected from ANI0 to
Remark ANI0 to ANI3: 78K0/KB2
By setting bit 7 (ADCS) of the A/D converter mode register (ADM) to 1, the A/D conversion operation of the voltage,
which is applied to the analog input pin specified by the analog input channel specification register (ADS), is started.
When A/D conversion has been completed, the result of the A/D conversion is stored in the A/D conversion result
register (ADCR), and an interrupt request signal (INTAD) is generated.
completed, the next A/D conversion operation is immediately started.
If ADS is rewritten during A/D conversion, the A/D conversion operation under execution is stopped and restarted
from the beginning.
If 0 is written to ADCS during A/D conversion, A/D conversion is immediately stopped. At this time, the conversion
result immediately before is retained.
