Bit 7 – RUNSTDBY Run in Standby Mode
| Value | Description |
|---|---|
| 0 | In Standby Sleep mode, the peripheral is halted |
| 1 | In Standby Sleep mode, the peripheral continues operation |
Bit 6 – OUTEN Analog Comparator Output Pad Enable
Bits 5:4 – INTMODE[1:0] Interrupt Modes
Writing to these bits selects what edges of the AC output triggers an interrupt request.
| Value | Name | Description |
|---|---|---|
| 0x0 | BOTHEDGE | Both negative and positive edge |
| 0x1 | - | Reserved |
| 0x2 | NEGEDGE | Negative edge |
| 0x3 | POSEDGE | Positive edge |
Bit 3 – LPMODE Low-Power Mode
Writing a '1' to this bit reduces the current through the comparator. This reduces the power consumption but increases the reaction time of the AC.
| Value | Description |
|---|---|
| 0 | Low-Power mode disabled |
| 1 | Low-Power mode enabled |
Bits 2:1 – HYSMODE[1:0] Hysteresis Mode Select
Writing these bits selects the Hysteresis mode for the AC input.
| Value | Name | Description |
|---|---|---|
| 0x0 | OFF | OFF |
| 0x1 | 10 | ±10 mV |
| 0x2 | 25 | ±25 mV |
| 0x3 | 50 | ±50 mV |
