FSK/OOK Description
rw
0x01 ₅^th _{byte of Sync word.}
* _{Used if SyncOn is set and (SyncSize +1) >= 5.}
rw
0x01 ₆^th _{byte of Sync word.}
* _{Used if SyncOn is set and (SyncSize +1) >= 6.}
rw
0x01 ₇^th _{byte of Sync word.}
* _{Used if SyncOn is set and (SyncSize +1) >= 7.}
rw
0x01 ₈^th _{byte of Sync word.}
* _{Used if SyncOn is set and (SyncSize +1) = 8.}
Defines the packet format used:
rw 0x01 0 Æ Fixed length
1 Æ Variable length
Defines DC-free encoding/decoding performed:
00 Æ None (Off)
rw 0x00 01 Æ Manchester
10 Æ Whitening
11 Æ reserved
Enables CRC calculation/check (Tx/Rx):
rw 0x01 0 Æ Off
1 Æ On
Defines the behavior of the packet handler when CRC check fails:
rw
0x00
0 Æ Clear FIFO and restart new packet reception. No
PayloadReady interrupt issued.
1 Æ Do not clear FIFO. PayloadReady interrupt issued.
Defines address based filtering in Rx:
00 Æ None (Off)
rw
0x00
01 Æ Address field must match NodeAddress
10 Æ Address field must match NodeAddress or
BroadcastAddress
11 Æ reserved
Selects the CRC and whitening algorithms:
rw 0x00 0 Æ CCITT CRC implementation with standard whitening
1 Æ IBM CRC implementation with alternate whitening
r
- unused
Data processing mode:
rw 0x01 0 Æ Continuous mode
1 Æ Packet mode
Enables the io-homecontrol^® compatibility mode
rw 0x00 _{0 Æ Disabled}
1 Æ 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
