15.5.3 Trigger mode
software trigger mode and hardware trigger modes. The hardware trigger modes include timer trigger modes 0 and 1, and
external trigger mode. The ADA0M0.ADA0TMD bit is used to set the trigger mode. The hardware trigger modes are set
by the ADA0M2.ADA0TMD1 and ADA0M2.ADA0TMD0 bits.

The timing of starting the conversion operation is specified by setting the trigger mode. The trigger mode includes the
(1) Software trigger mode
(2) External trigger mode
When the ADA0M0.ADA0CE bit is set to 1, the signal of the analog input pin (ANI0 to ANI11 pin) specified by the
ADA0S register is converted. When conversion is complete, the result is stored in the ADA0CRn register. At the
same time, the A/D conversion end interrupt request signal (INTAD) is generated.
If the operation mode specified by the ADA0M0.ADA0MD1 and ADA0M0.ADA0MD0 bits is the continuous
select/scan mode, the next conversion is repeated, unless the ADA0CE bit is cleared to 0 after completion of the
conversion. Conversion is performed once and ends if the operation mode is the one-shot select/scan mode.
When conversion is started, the ADA0M0.ADA0EF bit is set to 1 (indicating that conversion is in progress).
If the ADA0M0, ADA0M2, ADA0S, ADA0PFM, or ADA0PFT register is written during conversion, the conversion is
aborted and started again from the beginning. However, writing to these registers is prohibited in the normal
conversion mode and one-shot select mode/one-shot scan mode in the high-speed conversion mode.
In this mode, converting the signal of the analog input pin (ANI0 to ANI11) specified by the ADA0S register is
started when an external trigger is input (to the ADTRG pin). Which edge of the external trigger is to be detected
(i.e., the rising edge, falling edge, or both rising and falling edges) can be specified by using the
ADA0M0.ADA0ETS1 and ADA0M0.ATA0ETS0 bits. When the ADA0CE bit is set to 1, the A/D converter waits for
the trigger, and starts conversion after the external trigger has been input.
When conversion is completed, the result of conversion is stored in the ADA0CRn register, regardless of whether
the continuous select, continuous scan, one-shot select, or one-shot scan mode is set as the operation mode by
the ADA0MD1 and ADA0MD0 bits. At the same time, the INTAD signal is generated, and the A/D converter waits
for the trigger again.
When conversion is started, the ADA0EF bit is set to 1 (indicating that conversion is in progress). While the A/D
converter is waiting for the trigger, however, the ADA0EF bit is cleared to 0 (indicating that conversion is stopped).
If the valid trigger is input during the conversion operation, the conversion is aborted and started again from the
beginning.
If the ADA0M0, ADA0M2, ADA0S, ADA0PFM, or ADA0PFT register is written during the conversion operation, the
conversion is aborted, and the A/D converter waits for the trigger again. However, writing to these registers is
prohibited in the one-shot select mode/one-shot scan mode.
Caution To select the external trigger mode, set the high-speed conversion mode. Do not input a trigger
Remark
during the stabilization time that is inserted once after the A/D conversion operation is enabled
(ADA0M0.ADA0CE bit = 1).
The trigger standby status means the status after the stabilization time has elapsed.
