It is possible to reset triangle wave generation by resetting the WAVEx[1:0] bits.

MAMPx[3:0] max amplitude

+ DAC_DHRx base value

DAC_DHRx base value

The DAC trigger must be enabled for noise generation by setting the TENx bit in the

DAC_CR register.

The MAMPx[3:0] bits must be configured before enabling the DAC, otherwise they cannot

Dual DAC channel conversion

To efficiently use the bus bandwidth in applications that require the two DAC channels at the

same time, three dual registers are implemented: DHR8RD, DHR12RD and DHR12LD. A

unique register access is then required to drive both DAC channels at the same time.

Eleven possible conversion modes are possible using the two DAC channels and these dual

registers. All the conversion modes can nevertheless be obtained using separate DHRx

registers if needed.

All modes are described in the paragraphs below.
