RegFifoThresh (0x3C)
7
TxStartCondition
rw
1
*
Defines the condition to start packet transmission :
0 FifoLevel (i.e. the number of bytes in the FIFO
exceeds FifoThreshold)
1 → FifoNotEmpty (i.e. at least one byte in the FIFO)
6-0
FifoThreshold
rw
000111
Used to trigger FifoLevel interrupt.
RegPacketConfig2
(0x3D)
7-4
InterPacketRxDelay
rw
0000
After PayloadReady occurred, defines the delay between
FIFO empty and the start of a new RSSI phase for next
packet. Must match the transmitter‟s PA ramp-down
time.
- Tdelay = 0 if InterpacketRxDelay >= 12
- Tdelay = (2InterpacketRxDelay) / BitRate otherwise
3
-
rw
0
unused
2
RestartRx
w
0
Forces the Receiver in WAIT mode, in Continuous Rx
mode.
Always reads 0.
1
AutoRxRestartOn
rw
1
Enables automatic Rx restart (RSSI phase) after
PayloadReady occurred and packet has been completely
read from FIFO:
0 → Off. RestartRx can be used.
1 On. Rx automatically restarted after
InterPacketRxDelay.
0
AesOn
rw
0
Enable the AES encryption/decryption:
0 → Off
1 → On (payload limited to 66 bytes maximum)
