12.7.2 Continuous scan mode/one-shot scan mode operations
ANIn0 pin using the ADTRGn signal as a trigger, and A/D converted continuously. The A/D conversion results are
stored in the ADAnCRm register corresponding to the analog input pin
(INTADn) is generated. After the end of A/D conversion, the A/D converter waits for a trigger.
In this mode, the analog input pins (ANInm)
When conversion of all the specified analog input pins
This is most suitable for applications in which multiple analog inputs are constantly monitored.
Note Only the ANI00 and ANI01 pins can be used when A/D converter 0 of the V850E/IA3 is used.
Remark
Remark
(1) The ADA0CE bit = 1 (enable)
(2) The external trigger signal (ADTRG0) is generated
(3) The ANI00 pin is A/D converted
(4) The conversion result is stored in the ADA0CR0 register (11) The ADA0M0.ADA0EF bit = 0
(5) The ANI01 pin is A/D converted
(6) The conversion result is stored in the ADA0CR1 register (13) If next trigger is input, return to (3)
(7) The ANI02 pin is A/D converted
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 = 01 or 11, ADA0M0.ADA0TMD bit = 1,
ADA0M2.ADA0BS bit = 0, ADA0M2.ADA0TMD1 and ADA0M2.ADA0TMD0 bits = 00,
ADA0S.ADA0S2 to ADA0S.ADA0S0 bits = 011
