Bits 31:29 Reserved, must be kept at reset value.
Bit 28 Reserved, must be kept at reset value.
Bit 27 Reserved, must be kept at reset value.
Bits 26:16 Reserved, must be kept at reset value.
Bit 15 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:There is no write operation of DAC_SHSR1 ongoing: DAC_SHSR1 can be written
1:There is a write operation of DAC_SHSR1 ongoing: DAC_SHSR1 cannot be written
Bit 14 CAL_FLAG1: DAC channel1 calibration offset status
This bit is set and cleared by hardware
0: calibration trimming value is lower than the offset correction value
1: calibration trimming value is equal or greater than the offset correction value
