Bit 15 – DACEN Individual DACx Module Enable bit
| Value | Description |
|---|---|
| 1 | Enables DACx module |
| 0 | Disables DACx module to reduce power consumption; any pending Slope mode and/or underflow conditions are cleared |
Bits 14:13 – IRQM[1:0] Interrupt Mode select bits
| Value | Description |
|---|---|
| 11 | Generates an interrupt on either a rising or falling edge detect |
| 10 | Generates an interrupt on a falling edge detect |
| 01 | Generates an interrupt on a rising edge detect |
| 00 | Interrupts are disabled |
Bit 10 – CBE Comparator Blank Enable bit
| Value | Description |
|---|---|
| 1 | Enables the analog comparator output to be blanked (gated off) during the recovery transition following the completion of a slope operation |
| 0 | Disables the blanking signal to the analog comparator; therefore, the analog comparator output is always active |
Bit 9 – DACOEN DACx Output Buffer Enable bit
| Value | Description |
|---|---|
| 1 | DACx analog voltage is connected to the DACOUTx pin |
| 0 | DACx analog voltage is not connected to the DACOUTx pin |
Bit 8 – FLTREN Comparator Digital Filter Enable bit
| Value | Description |
|---|---|
| 1 | Digital filter is enabled |
| 0 | Digital filter is disabled |
Bit 7 – CMPSTAT Comparator Status bit
Bit 6 – CMPPOL Comparator Output Polarity Control bit
| Value | Description |
|---|---|
| 1 | Output is inverted |
| 0 | Output is noninverted |

Bit 2 – HYSPOL Comparator Hysteresis Polarity Select bit
| Value | Description |
|---|---|
| 1 | Hysteresis is applied to the falling edge of the comparator output |
| 0 | Hysteresis is applied to the rising edge of the comparator output |
Bits 1:0 – HYSSEL[1:0] Comparator Hysteresis Select bits
| Value | Description |
|---|---|
| 11 | 45 mv hysteresis |
| 10 | 30 mv hysteresis |
| 01 | 15 mv hysteresis |
| 00 | No hysteresis is selected |
