values:
LL_DAC_TRIG_SOFTWARE
LL_DAC_TRIG_EXT_TIM8_TRGO
LL_DAC_TRIG_EXT_TIM7_TRGO
LL_DAC_TRIG_EXT_TIM6_TRGO

None:
Notes
For conversion trigger source to be effective, DAC trigger
must be enabled using function LL_DAC_EnableTrigger().
To set conversion trigger source, DAC channel must be
disabled. Otherwise, the setting is discarded.
Availability of parameters of trigger sources from timer
depends on timers availability on the selected device.
