Wakeup control
| WAKEUP_INSTANT | Instant, with reference to the internal 16-bit clock reference, at which the hardware must wakeup from deep sleep mode. This is calculated by firmware based on the next closest instant where a controller operation is required (like advertiser/scanner). Firmware reads the next instant of the procedures in the corresponding *_NEXT_INSTANT registers. This value is used only when hardware auto wakeup from deep sleep mode is enabled in the clock control register. Note: it is recommended to program wakeup_instant such a way that the actual instant to wakeup shall be at least two counts (two slots of 625 us) ahead of reference clock when entering DSM. The actual instant to wakeup is 'wakeup_instant - dsm_offset_to_wakeup_instant - osc_startup_delay, and it shall be greater than ‘reference clock + 2’ |
