13.4.2 Trigger mode
Trigger mode that serve as the start timing of an A/D conversion operation is software trigger mode.
This mode is set by the AD2M0 register.
(1) Software trigger mode
Remark
In this mode, the analog input pin (ANI2n) specified by the AD2S.AD2S2 to AD2S.AD2S0 bits is used for the
A/D conversion start timing by setting the AD2M0.AD2CE bit to 1.
After A/D conversion ends, the conversion result is stored in A/D2 conversion result register n (AD2CRn).
An A/D2 conversion end interrupt request signal (INTAD2) is generated simultaneously when A/D conversion
operations are completed in the select mode. INTAD2 interrupt request signal is generated when all the
specified A/D conversion operations are completed in the scan mode.
If the operation mode set by the AD2M0.AD2MD1 and AD2M0.AD2MD0 bits is the continuous select mode or
continuous scan mode, the conversion operation is repeated unless the AD2M0.AD2CE bit is set to 0. In the
one-shot select mode or one-shot scan mode, the conversion operation is stopped after A/D conversion ends.
The AD2M0.AD2EF bit is set to 1 (conversion in progress) when A/D conversion is started, and set to 0
(conversion stops) when it is completed.
If the AD2M0 and AD2S registers are written during A/D conversion, the conversion is stopped and executed
again from the beginning.
