4.3.2. Sequencer Transitions
The transitions between states are listed in the forthcoming table.
Table 22 Sequencer Transition Options
Variable

SequencerLowPowerState
SequencerTransitionFromLowPower
SequencerTransitionFromTransmit
SequencerTransitionFromReceive
SequencerTransitionFromRxTimeout
SequencerTransitionFromPacketReceived
Transition
Control state-machine transition from the Idle state:
00: to LowPower or Idle state on a SequencerStart command, depending on
SequencerLowPowerState
01: to Receive state on a SequencerStart command
10: to Transmit state on a SequencerStart command
11: to WaitForFifo on a SequencerStart command
Defines the low power state of the Sequencer, reached at the end of any action
(transmission, reception, etc...)
0: to Idle state
1: to LowPower state
Control the Sequencer transition from the LowPower state:
0: to Transmit state on a Timer 1 interrupt
1: to Receive state on a Timer 1 interrupt
Control the Sequencer transition from the Transmit state:
0: to LowPower or Idle state on a PacketSent interrupt, depending on
SequencerLowPowerState
1: to Receive state on a PacketSent interrupt
Control the Sequencer transition from the Receive state
000 and 111: unused
001: to PacketReceived state on a PayloadReady interrupt
010: to LowPower or Idle state on a PayloadReady interrupt, depending on
SequencerLowPowerState
011: to PacketReceived state on a CrcOk interrupt. If the CRC is disabled the
PayloadReady interrupt, firing when enough bytes are received, will drive the
Sequencer to the PacketReceived state, too.
100: to Idle state on a Rssi interrupt
101: to Idle state on a SyncAddress interrupt
110: to Idle state on a PreambleDetect interrupt
Irrespective of this setting, transition to LowPower or Idle state on a Timer2
interrupt, depending on SequencerLowPowerState
Control the state-machine transition from the Receive state on a RxTimeout
interrupt (and on PayloadReady if SequencerTransitionFromReceive = 011):
00: to ReceiveRestart
01: to Transmit
10: to LowPower or Idle state, depending on SequencerLowPowerState
11: to Idle state
Control the state-machine transition from the PacketReceived state:
000: to Idle state
001: to Transmit on a FifoEmpty interrupt
010: to LowPower or Idle state on FifoEmpty, depending on
SequencerLowPowerState
011: to Receive via FS mode, if frequency was changed
100: to Receive state (no frequency change)
