Bit 31 – SHEN1 Comparator1 DAC1 Sample and Hold Enable Operating Mode
This bit enabled the odd DAC low-power operation.
Note: If DACCTRLn.SHENn=1 user must initialize AC.CTRLC.PER and AC.CTRLC.WIDTH
accordingly.
| Value | Description |
|---|---|
| 0 | Continuous operation mode is enabled. |
| 1 | Sample-and-hold operation mode is enabled. |
Bits 22:16 – VALUE1[6:0] Comparator1 DAC1 Output Value
These bits define the scaling factor for odd DAC channel voltage reference. The output voltage, VOUT, is:
Bit 15 – SHEN0 Comparator0 DAC0 Sample and Hold Enable Operating Mode
This bit enabled the even DAC low-power operation.
Note: If DACCTRLn.SHENn=1 user must initialize AC.CTRLC.PER and AC.CTRLC.WIDTH
accordingly.
| Value | Description |
|---|---|
| 0 | Continuous operation mode is enabled. |
| 1 | Sample-and-hold operation mode is enabled. |
Bits 6:0 – VALUE0[6:0] Comparator0 DAC0 Output Value
These bits define the scaling factor for even DAC channel voltage reference. The output voltage, VOUT, is:
These bits can be written only while COMPCTRL(2n).ENABLE is zero.
