(1) Interval operation

[RX]

After wake-up, RX_ON state. If continuous operation timer completed before SyncWord detection,

automatically move to SLEEP state. If SyncWord detected, continue RX_ON. After RX completion, conitune

operation defined by RXDONE_MODE[1:0] ([RF_STATUS_CTRL:B0 0x0A(3-2)]).

[TX]

After wake-up, TX_ON state. After TX completion, continue operation defined by TXDONE_MODE[1:0]

([RF_STATUS_CTRL: B0 0x08(1-0)]) .

If continuous operation timer completed, automatically return to SLEEP state. So continuous operation timer

has to be set so that timer completion occur after TX completion.
