Description
Default
The delay added to the output voltage
of SPKFB for synchronization.
nDelay = reg[0xa4] / 2^21
0
The range is [-2, 3) with 21 fractional
bits.
The initial value of the parameter
which is propotional to the resistance.
Resistance = reg[0xa5] / 2^23
The range is [0, 2) with 23 fractional
bits.
24'h800000
The initial value of the radians for the ^24'hC4266F
adaptive filter.
24'h345F58
The radians π/2 is normalized to 1/2,
and the range is [-0.5, 0.5] with 23 ^24'hFE21CB
fractional bits.
