Device wake configuration register
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| WAKE_PULSE_CONFIG | WAKE_SENSE | TWK_CYC_SET | nINT_SEL | RXD_WK_CONFIG | WAKE_LEVEL | ||

| Bit | Field | Type | Reset | Description |
|---|---|---|---|---|
| 7 | WAKE_PULSE_CONFIG | R/W | 0b | Set WAKE pin expected pulse direction 0b = Low –> High –> Low 1b = High –> Low –> High |
| 6 | WAKE_SENSE | R/W/H | 0b | WAKE pin configured for static or cyclic sensing wake 0b = Static 1b = Cyclic Note: When Cyclic sensing is selected and the device goes to fail-safe mode it will automatically change to static sensing. If cyclic sensing is needed it will have to be reprogrammed. |
| 5 | TWK_CYC_SET | R/W | 0b | Sets the tWK_CYC time (μs) for sampling the WAKE pin status (used for cyclic sensing) 0b = 30 1b = 75 Note: NOTE: tWK_CYC_SET works with timer1 and timer2. When using 75 μs tWK_CYC, 100 μs TIMER1/2_ON_WIDTH cannot be used. |
| 4-3 | nINT_SEL | R/W | 00b | nINT configuration selection: active low 00b = Global interrupt 01b = Watchdog failure output 10b = Reserved 11b = Wake request |
| 2 | RXD_WK_CONFIG | R/W | 0b | Configures RXD pin behavior from a wake event 0b = Pulled low 1b = Toggle |
| 1-0 | WAKE_LEVEL | R/W | 10b | WAKE pin threshold level; Mid-point value in 2 V window. 00b = 2.5 V 01b = 2.8 V 10b = 3 V 11b = 3.3 V |
