(3) Timer trigger mode
If the ADA0M0, ADA0M2, ADA0S, ADA0PFM, or ADA0PFT register is written during conversion, 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 (n = 0 to 11).
Caution When selecting the external trigger mode, set the high-speed conversion mode. Do not input
Remark
In this mode, converting the signal of the analog input pin (ANI0 to ANI11) specified by the ADA0S register is
started by the compare match interrupt request signal (INTTP2CC0 or INTTP2CC1) of the capture/compare
register connected to the timer. The INTTP2CC0 or INTTP2CC1 signal is selected by the ADA0TMD1 and
ADA0TMD0 bits, and conversion is started at the rising edge of the specified compare match interrupt request
signal. When the ADA0CE bit is set to 1, the A/D converter waits for a trigger, and starts conversion when the
compare match interrupt request signal of the timer is input.
When conversion is completed, 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, the result of the
conversion is stored in the ADA0CRn register. 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 a valid trigger is input during conversion, the conversion is aborted and started again from the
beginning.
If the ADA0M0, ADA0M2, ADA0S, ADA0PFM, or ADA0PFT register is written during conversion, the conversion
is stopped 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 When selecting the timer trigger mode, set the high-speed conversion mode. Do not input a
