4.4. AutoModes
Automatic modes of packet handler can be enabled by configuring the related parameters in RegAutoModes.
The intermediate mode of the chip is called IntermediateMode and the enter and exit conditions to/from this intermediate
mode can be configured through the parameters EnterCondition & ExitCondition.
The enter and exit conditions cannot be used independently of each other i.e. both should be enabled at the same time.
The initial and the final state is the one configured in Mode in RegOpMode. The initial & final states can be different by
configuring the modes register while the chip is in intermediate mode. The pictorial description of the auto modes is shown
below.

Figure 23. Auto Modes of Packet Handler
Some typical examples of AutoModes usage are described below:
 Automatic transmission (AutoTx) : Mode = Sleep, IntermediateMode = Tx, EnterCondition = FifoLevel, ExitCondition =
PacketSent
 Automatic reception (AutoRx) : Mode = Rx, IntermediateMode = Sleep, EnterCondition = CrcOk, ExitCondition = falling
edge of FifoNotEmpty
 Automatic reception of acknowledge (AutoRxAck): Mode = Tx, IntermediateMode = Rx, EnterCondition = PacketSent,
ExitCondition = CrcOk
