(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) is A/D converted four times using the A/D 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.
Remark
(motor control function) is generated
