DAC status register
| DMAUDR1 | DAC channel1 DMA underrun flag This bit is set by hardware and cleared by software (by writing it to 1). 0 (B_0x0): No DMA underrun error condition occurred for DAC channel1 1 (B_0x1): DMA underrun error condition occurred for DAC channel1 (the currently selected trigger is driving DAC channel1 conversion at a frequency higher than the DMA service capability rate) |
| CAL_FLAG1 | DAC channel1 calibration offset status This bit is set and cleared by hardware 0 (B_0x0): calibration trimming value is lower than the offset correction value 1 (B_0x1): calibration trimming value is equal or greater than the offset correction value |
| BWST1 | DAC channel1 busy writing sample time flag This bit is systematically set just after Sample and hold mode enable and is set each time the software writes the register DAC_SHSR1, It is cleared by hardware when the write operation of DAC_SHSR1 is complete. (It takes about 3 LSI periods of synchronization). 0 (B_0x0): There is no write operation of DAC_SHSR1 ongoing: DAC_SHSR1 can be written 1 (B_0x1): There is a write operation of DAC_SHSR1 ongoing: DAC_SHSR1 cannot be written |
| DMAUDR2 | DAC channel2 DMA underrun flag This bit is set by hardware and cleared by software (by writing it to 1). Note: This bit is available only on dual-channel DACs. Refer to implementation. 0 (B_0x0): No DMA underrun error condition occurred for DAC channel2 1 (B_0x1): DMA underrun error condition occurred for DAC channel2 (the currently selected trigger is driving DAC channel2 conversion at a frequency higher than the DMA service capability rate). |
