FSK/OOK Description
Defines the packet format used:
rw 0x01 0 Fixed length
1 Variable length
Defines DC-free encoding/decoding performed:
00 None (Off)
rw 0x00 01 Manchester
10 Whitening
11 reserved
Enables CRC calculation/check (Tx/Rx):
rw 0x01 0 Off
1 On
Defines the behavior of the packet handler when CRC check fails:
rw
0x00
0 Clear FIFO and restart new packet reception. No
PayloadReady interrupt issued.
1 Do not clear FIFO. PayloadReady interrupt issued.
Defines address based filtering in Rx:
00 None (Off)
rw
0x00
01 Address field must match NodeAddress
10 Address field must match NodeAddress or
BroadcastAddress
11 reserved
Selects the CRC and whitening algorithms:
rw 0x00 0 CCITT CRC implementation with standard whitening
1 IBM CRC implementation with alternate whitening
r
- unused
Data processing mode:
rw 0x01 0 Continuous mode
1 Packet mode
Enables the io-homecontrol® compatibility mode
rw 0x00 0 Disabled
1 Enabled
rw 0x00 reserved - Linked to io-homecontrol® compatibility mode
rw 0x00 Enables the Beacon mode in Fixed packet format
rw 0x00 Packet Length Most significant bits
rw
0x40
If PacketFormat = 0 (fixed), payload length.
If PacketFormat = 1 (variable), max length in Rx, not used in Tx.
rw 0x00 Node address used in address filtering.
rw 0x00 Broadcast address used in address filtering.
