FSK/OOK Description
Controls the Sequencer transition from the Receive state
000 and 111: unused
001: to PacketReceived state on a PayloadReady interrupt
010: to LowPowerSelection on a PayloadReady interrupt
011: to PacketReceived state on a CrcOk interrupt (1)
100: to SequencerOff state on a Rssi interrupt
101: to SequencerOff state on a SyncAddress interrupt
rw 0x00 110: to SequencerOff state on a PreambleDetect interrupt
Irrespective of this setting, transition to LowPowerSelection on a
T2 interrupt
(1) If the CRC is wrong (corrupted packet, with CRC on but
CrcAutoClearOn=0), the PayloadReady interrupt will drive the
sequencer to RxTimeout state.
Controls the state-machine transition from the Receive state on a
RxTimeout interrupt (and on PayloadReady if FromReceive =
011):
00: to Receive State, via ReceiveRestart
rw
0x00
01: to Transmit state
10: to LowPowerSelection
11: to SequencerOff state
Note: RxTimeout interrupt is a TimeoutRxRssi,
TimeoutRxPreamble or TimeoutSignalSync interrupt
Controls the state-machine transition from the PacketReceived
state:
000: to SequencerOff state
rw 0x00 001: to Transmit state on a FifoEmpty interrupt
010: to LowPowerSelection
011: to Receive via FS mode, if frequency was changed
100: to Receive state (no frequency change)
