11.4.2 Trigger mode
Several conversion operations can be specified for A/D converter by specifying operation modes and
trigger modes. Those modes are set using bits PLM, TRG0 and TRG1 of A/D conversion mode
register 0 (ADSCM0H).
There are two trigger modes, the software trigger mode and the external trigger mode.
The relationship between operation modes, software and external trigger modes is shown below.
Note: ADSCM0H.MS bit selects either the scan mode (MS= 0) or the select mode (MS=1) for each
