Same interface mode as the CDL40 Series.
SBSO is output from SQSO pin. In other words, subcodes P to W are
read out from SQSO. Input the read clock to SQCK.
SENS is output from SQSO pin.
Each output signal is output from SQSO pin.
Input the read clock to SQCK.
(See to Timing Chart 1-4.)

$BX commands
This command switches the method of interfacing with the CPU. With the CDL500 Series, the number of
signal lines between the CPU and the DSP can be reduced in comparison with the CDL40 Series. Also, the
error rate can be measured with the CPU.
$CX commands
CLVS mode gain setting: GCLVS
CLVP mode gain setting: GMDP, GMDS
Servo coefficient setting
