// Output value
uint16_t data3
// Output value
);
Description
Enable the DAC module and set the operating conditions.
[data1]

parameters data2 and data3.
Left: padded at the MSB end.
Right: padded at the LSB end.
[data2]
The value to be written to the channel 0 output register. Ignored if the channel is not enabled.
