Deep Software Standby

When the SSBY bit in SBYCR has been set to 1,

executing the SLEEP instruction causes a transition to

software standby mode. At this time, if there is no source

to clear software standby mode and this bit is set to 1, a

transition to deep software standby mode is made.

Enters deep software standby

mode after execution of a SLEEP

instruction.

When deep software standby mode is canceled due to an

interrupt, this bit remains at 1. Write a 0 here to clear it.

Setting of this bit has no effect when the WDT is used in

watchdog timer mode. In this case, executing the SLEEP

instruction always initiates entry to sleep mode or all-

module-clock-stop mode. Be sure to clear this bit to 0

when setting the SLPIE bit to 1.
