Trigger mode is enabled by setting DACC_TRIGR.TRGENx.
The conversion waits for a rising edge on the selected trigger to send the data to the DAC. In this mode, the maximum data rate (i.e., the maximum trigger event frequency) cannot exceed 12 DAC clock periods plus 2 cycles of resynchronization stage.
Note: Disabling Trigger mode (TRGENx = 0) automatically sets the DACC in Free-running or Max
speed mode depending on the status of DACC_MR.MAXSx.
