* @brief Enter deep sleep mode
*
* Similar to rtc_sleep_start(), but additionally uses hardware to calculate the CRC value
* of RTC FAST memory. On wake, this CRC is used to determine if a deep sleep wake
* stub is valid to execute (if a wake address is set).
*
* No RAM is accessed while calculating the CRC and going into deep sleep, which makes
* this function safe to use even if the caller's stack is in RTC FAST memory.
*
* @note If no deep sleep wake stub address is set then calling rtc_sleep_start() will
* have the same effect and takes less time as CRC calculation is skipped.
*
* @note This function should only be called after rtc_sleep_init() has been called to
* configure the system for deep sleep.
*
* @param wakeup_opt - same as for rtc_sleep_start
* @param reject_opt - same as for rtc_sleep_start
*
* @return non-zero if sleep was rejected by hardware
