R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Scrambler seed for long preamble
bit 3 of CR5 selects CR36 or CR 37
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
Scrambler seed for short preamble
bit 3 of CR5 selects CR36 or CR 37
CR_AGC_EDmode.
0 = noise floor + CR_AGC_EDthresh
1 = absolute threshold
CR_AGC_EDthresh. Energy detect threshold, (range 0-127)
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 of 2. Set to 00h to disable scaling.
Threshold. RSSI below this threshold will result in an antenna search.
0 = threshold is relative to noise floor
1 = threshold is absolute
Threshold for antenna decision (CR_AGC_AntSearchThresh), range 0-127
R/W but not currently used internally, should be set to zero to ensure compatibility with future revisions.
