CIC STAGES. Number of CIC integrator/comb pairs (1-5). Stages are enabled starting with the largest accumulator.
000 = 1 stage;
001 = 2 stages;
010 = 3 stages;
011 = 4 stages;
100 = 5 stages;
Load with the number of stages minus 1.
CIC DECIMATION FACTOR. Load with (decimation - 1).
UNUSED.
PN LEVEL. Level of the PN generator data that is added to the mixer output when the PN generator is enabled in IWA = *001h, bit 16.
UNUSED.
DECIMATION OF THE RESAMPLER DECIMATOR BLOCK. Load with the desired decimation factor minus one.
000 = Decimation of 1
111 = Decimation of 8
RESERVED. Set to 0.
FIR2 REQUIRED CLOCKS. This value should be set to: ceil (#TAPS/8) - 1.
RESERVED. Set to 0.
FIR2 DECIMATION. Available decimation through FIR2 block is 1-8. Set the value to: decimation factor - 1.
FIR1 ENABLE HBF MODE.
1 = Half Band Filter mode.
0 = normal mode.
FIR1 REQUIRED CLOCKS. Set to:
ceil (#TAPS/4) - 1.
RESERVED. Set to 0.
FIR1 DECIMATION. Available decimation through FIR1 block is 1-8. Set the value to: decimation factor - 1.
UNUSED.
RESERVED. Set to 0.
REAL TIME AGC GAIN OUTPUT SOURCE.
0 = the continuously updated loop filter output is provided to the output section as the “real time” AGC gain.
1 = the sampled loop filter output (sampled when the interval count is 0) is provided to the output section as the “real time” AGC gain.
DATA DELAY. This value is the number of samples that data is delayed to allow for AGC settling.
0x00 = no delay.
0x3F = 1 sample
. . .
0x01 = 63 samples.
LOOP GAIN 1 MEAN/MEDIAN.
1 = AGC settles to mean of the signal if LG1 is selected.
0 = AGC settles to median of the signal.
