7-2 (5) EDATA error rate monitor function
The error rate can be monitored through the STAT pin. The error rate is the number of frames (FLAG0=H),
where C1 errors are detected, out of 2048 frames of data. The rate monitored is within an output
range between 0 and 255.
By changing the command, the number of interpolation flag (IPFLAG) signals out of 2048 frames
of data is monitored within an output range between 0 and 255.

Flag D7 D6 D5 D4 D3 D2 D1 D0
The EDATA output command 7Ah is input after setting the EDATA change command in 46h(b9).
The flag must be checked after the point of the flag definite delay.
If the flag is set to L level, there is no need to read the error rate data because the rate is the same as the
error rate data previously read.
Input the MCLK signal and read the error rate if the flag is set to H level.
