Or, when Vref=Vcc=5V, do not uses codes above 800.
4. DAC Update in Autotrig mode
If the cpu writes in DACH register at the same instant that the selected trigger source occurs
and DAC Auto Trigger is enabled, the DACH register is not updated by the new value.
Work around: .
When using the autotrig mode, write twice in the DACH register. The time between the two
CPU writes, must be different than the trigger source frequency.
