Descriptions
This is the relative threshold to shut down the (G)FSK
demodulation. It is measured in terms of RSSI code. The
range is from 0 to 255.
Turn on/off the Automatic Frequency Control function.
The options are: On or Off.
The data acquisition mode, the options are: Direct, Buffer
or Packet.
The device can support two packet types. The options
are: Fixed length or Variable length.
This defines the FIFO threshold that once it is reached,
an interrupt is generated to notify the external MCU. The
range is from 1 to 32, in terms of the FIFO address.
This parameter is only available when DC-Free Data
Decode is not set to “None”. The initial seed for the data
de-whitening polynomial. The range is from 0 to 255.
The options of DC-free data decoding are None,
Manchester 1 (01=one, 10=zero), Manchester 2 (10=
one, 01=zero), or Data De-whitening.
The size of the valid preamble, the options are: None,
1-byte, 2-byte, 3-byte, or 4-byte.
The size of the Sync Word, the options are: None, 1-byte,
2-byte, 3-byte, or 4-byte. This option cannot be set to
“None” in buffer mode.
This parameter is only available when Sync Size is not
set to “None”. It defines the value of the Sync Word, the
range is from 0 to 2^N-1, where N is determined by Sync
Size. For example, if Sync Size is 1-byte, N is 8; if Sync
Size is 2-byte, N is 16, etc.
The number of bits tolerated for the Sync Word
recognition. The options are: None, 1 Error, 2 Errors or 3
Errors.
The options for the Node ID detection are: None, Detect
Node ID, Detect Node ID and 0x00, or Detect Node ID,
0x00 and 0xFF
This parameter is only available when the Node ID
Options is not set to “None”. It defines the value of the
Node ID. The range is from 0 to 255.
This defines the number of bytes of data in a fixed length
packet. The range is from 0 to 32.

CRC Seed
This parameter is only available when CRC Options is not
set to “None”. It defines the initial seed for the CRC
NA
polynomial. The range is from 0 to 65535.
