Bit 31 Reserved, must be kept at reset value.
Bit 30 CEN2: DAC channel2 calibration enable
This bit is set and cleared by software to enable/disable DAC channel2 calibration, it can be
written only if EN2 bit is set to 0 into DAC_CR (the calibration mode can be entered/exit only
when the DAC channel is disabled) Otherwise, the write operation is ignored.
0: DAC channel2 in Normal operating mode
1: DAC channel2 in calibration mode
Note: This bit is available only on dual-channel DACs. Refer to Section 22.3: DAC
implementation.
Bit 29 DMAUDRIE2: DAC channel2 DMA underrun interrupt enable
This bit is set and cleared by software.
0: DAC channel2 DMA underrun interrupt disabled
1: DAC channel2 DMA underrun interrupt enabled
Note: This bit is available only on dual-channel DACs. Refer to Section 22.3: DAC
implementation.
Bit 28 DMAEN2: DAC channel2 DMA enable
This bit is set and cleared by software.
0: DAC channel2 DMA mode disabled
1: DAC channel2 DMA mode enabled
Note: This bit is available only on dual-channel DACs. Refer to Section 22.3: DAC
implementation.
