12.6.2 Continuous scan mode/one-shot scan mode operations
the ANIn0 pin using the A/D conversion start trigger from the timer (motor control function) as a trigger and A/D
conversion is performed 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 these modes, the analog input pins (ANInm)
When conversion of all the specified analog input pins
This mode is suitable for applications in which multiple analog input pins are constantly monitored.
In the continuous scan mode or one-shot scan mode, only the 1-buffer mode is supported.
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 A/D conversion start trigger signal from the timer
(3) The ANI00 pin is A/D converted
(4) The conversion result is stored in the ADA0CR0 register (11) If next trigger is input, return to (3)
(5) The ANI01 pin is A/D converted
(6) The conversion result is stored in the ADA0CR1 register
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 = 01 or 10,
ADA0S.ADA0S2 to ADA0S.ADA0S0 bits = 010
