12.7.1 Continuous select mode/one-shot select mode operations
results are stored in the ADAnCRm register. In the continuous select mode or one-shot select mode, there are two
select modes: 1-buffer mode and 4-buffer mode, according to the method of storing the A/D conversion results.
In these modes, the analog input pin (ANInm)
Note Only the ANI00 and ANI01 pins can be used when A/D converter 0 of the V850E/IA3 is used.
Remark
(1) 1-buffer mode (1 buffer of continuous select/one-shot select by external trigger)
Remark
(1) The ADA0CE bit = 1 (enable)
(2) The external trigger signal (ADTRG0) is generated
(3) The ANI02 pin is A/D converted
(4) The conversion result is stored in the ADA0CR2 register (8) To end the conversion, the ADA0CE bit = 0 (stop)
In this mode, the voltage of one analog input pin (ANInm)
as a trigger. The conversion results are stored in one ADAnCRm register. The ANInm pin
ADAnCRm register correspond one to one.
The A/Dn conversion end interrupt request signal (INTADn) is generated for each A/D conversion. After the
end of A/D conversion, the A/D converter waits for a trigger
This mode is suitable for applications in which the results of each first-time A/D conversion are read.
Note Only the ANI00 and ANI01 pins can be used when A/D converter 0 of the V850E/IA3 is used.
Remark
Note Only the ANI00 and ANI01 pins can be used when A/D converter 0 of the V850E/IA3 is used.

This is an operation example with the following setting.
ADA0M0.ADA0MD1 and ADA0M0.ADA0MD0 bits = 00 or 10, ADA0M0.ADA0TMD bit = 1,
ADA0M2.ADA0BS bit = 0, ADA0M2.ADA0TMD1 and ADA0M2.ADA0TMD0 bits = 00,
ADA0S.ADA0S2 to ADA0S.ADA0S0 bits = 010
