rw
0 Defines the packet format used:
0→ Fixed length
1→ Variable length
rw
00 Defines DC-free decoding performed:
00→ None (Off)
01→ Manchester
10→ Whitening
11→ reserved
rw
1 Enables CRC check:
0→ Off
1→ On
rw
0 Defines the behavior of the packet handler when CRC
check fails:
0→ Clear FIFO and restart new packet reception. No
PayloadReady interrupt issued.
1→ Do not clear FIFO. PayloadReady interrupt issued.
rw
00 Defines address based filtering in Rx:
00→ None (Off)
01→ Address field must match NodeAddress
10→ Must match NodeAddress or BroadcastAddress
11→ reserved
rw
0 unused
rw
0x40 If PacketFormat = 0 (fixed), payload length.
If PacketFormat = 1 (variable), max length in Rx
rw
0x00 Node address used in address filtering.
rw
0x00 Broadcast address used in address filtering.
rw
000 Interrupt condition for entering the intermediate mode:

010→ Rising edge of FifoLevel
011→ Rising edge of CrcOk
100→ Rising edge of PayloadReady
101→ Rising edge of SyncAddress
110→ Reserved
111→ Falling edge of FifoNotEmpty (i.e. FIFO empty)
rw
000 Interrupt condition for exiting the intermediate mode:
000→ None (AutoModes Off)
001→ Falling edge of FifoNotEmpty (i.e. FIFO empty)
010→ Rising edge of FifoLevel or Timeout
011→ Rising edge of CrcOk or Timeout
100→ Rising edge of PayloadReady or Timeout
101→ Rising edge of SyncAddress or Timeout
110→ Reserved
111→ Rising edge of Timeout
rw
00 Intermediate mode:
00→ Sleep mode (SLEEP)
01→ Standby mode (STDBY)
10→ Receiver mode (RX)
11→ Reserved
rw
1 unused
