CONFIGURATION REGISTER ADDRESS 34 (44h) R/W TEST BUS ADDRESS
Bits 7:0
address bits for various tests. See Tech Brief #TBD for a description of the factory test modes
CONFIGURATION REGISTER ADDRESS 35 (46h) R/W CMF COEFFICIENT CONTROL THRESHOLD
Bit 7
CMF Threshold control. Also controls CR49. This bit must be set to a “1” when using manual control of default and calculated
weights.
0 = threshold is relative to noise floor
1 = threshold is absolute.
Bits 6:0
Default weights RSSI Threshold. In half dB steps. This sets the SNR at which the decision to use either calculated or default
CMF weights is made in the absence of CW interference.
For 100% calculated weights, set to 80h and set CR49 to 00h.
For 100% default weights, set to ffh and set CR49 to 7fh.
CONFIGURATION REGISTER ADDRESS 36 (48h) R/W SCRAMBLER SEED LONG PREAMBLE
Bit 7
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Bit 6:0
Scrambler seed for long preamble
bit 3 of CR5 selects CR36 or CR 37
CONFIGURATION REGISTER ADDRESS 37 (4Ah) R/W SCRAMBLER SEED SHORT PREAMBLE
Bit 7
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Bit 6:0
Scrambler seed for short preamble
bit 3 of CR5 selects CR36 or CR 37
CONFIGURATION REGISTER ADDRESS 38 (4Ch) R/W ED THRESHOLD
Bit 7
CR_AGC_EDmode.
0 = noise floor + CR_AGC_EDthresh
1 = absolute threshold
Bit 7:0
CR_AGC_EDthresh. Energy detect threshold, (range 0-127)
CONFIGURATION REGISTER ADDRESS 39 (4Eh) R/W CMF SCALE THRESHOLD
Bit 7:6
Unused
Channel Matched filter scale threshold (range 0-255). After CMF is in operation, 8 correlation peaks are accumulated and
compared to threshold to determine if there is headroom to scale gain up by a factor. Set all to 03h to disable scaling.
Bits 5:4
Threshold for scaling gain by 2.5 if accumulated peak is less than:
00 = 10
01 = 20
10 = 30
11 = 40
Bits 3:2
Threshold for scaling gain by 1.5 if accumulated peak is less than:
00 = 20
01 = 50
10 = 60
11 = 70
Bits 1:0
Threshold for scaling gain by 0.5 if accumulated peak is less than:
00 = 250
01 = 350
10 = 450
11 = 750
CONFIGURATION REGISTER ADDRESS 40 (50h) R/W RSSI ANTENNA THRESHOLD
Bit 7
Threshold. RSSI below this threshold will result in an antenna search, above will result in sticking with the first antenna.
0 = threshold is relative to noise floor
1 = threshold is absolute
Bits 6:0
Threshold for antenna decision (CR_AGC_AntSearchThresh), range 0-127
