(2) 4-buffer mode operation (4 buffers of continuous select/one-shot select by timer trigger)
Remark
(1) The ADA0CE bit = 1 (enable)
(2) The A/D conversion start trigger signal from the timer
(3) The ANI02 pin is A/D converted
(4) The conversion result is stored in the ADA0CR0 register (12) The INTAD0 interrupt request signal is generated
(5) The ANI02 pin is A/D converted
(6) The conversion result is stored in the ADA0CR1 register (14) To end the conversion, the ADA0CE bit = 0 (stop)
(7) The ANI02 pin is A/D converted
A/D conversion start
trigger signal from timer
(motor control function)
In this mode, the voltage of one analog input pin (ANInm)
conversion start trigger signal from the timer (motor control function) as a trigger, and the results are stored in
the ADAnCRm register.
The A/Dn conversion end interrupt request signal (INTADn) is generated when the four A/D conversions end.
After the end of A/D conversion, the A/D converter waits for a trigger.
This mode is suitable for applications in which the average of the A/D conversion results is calculated.
Note Only the ANI00 and ANI01 pins can be used when A/D converter 0 of the V850E/IA3 is used.
Remark

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 = 1, ADA0M2.ADA0TMD1 and ADA0M2.ADA0TMD0 bits = 01 or 10,
ADA0S.ADA0S2 to ADA0S.ADA0S0 bits = 010
