(3) Combination with high speed carrier detection

[Intetval operation]

After wake-up timer completion, move to RX_ON state. Then perform CCA. If no carrier detected,

automatically move to SLEEP state. If carrier detected, maintaining RX_ON state and perform SuncWord

detection. If continuous operation timer completed before SyncWord detection, automatically move to SLEEP

state. And If SyncWord detected, continue RX_ON state.

[1 shot operation]

After wake-up timer completion, move to RX_ON state. And perform CCA to check carrier. If no carrier

detected, go back to SLEEP state automatically. After wake-up timer completion, wake-up to check the carrier

again. If carrier is detected, continue RX state. Able to go back to SLEEP by setting SLEEP parameters.
