(7) High speed carrier checking mode

This mode is used for deciding whether continuing RX state or stoping RX state during RX state, based on

RSSI level and SyncWord detection time. The value set in the [CCA_LVL:B0 0x37] register is used for RSSI

level decision, continuous operation timer is used for SyncWord detection time decision. After decision,

operation will automaticall switch to – either SLEEP state or RX state.
