Selects ON or OFF for muting and attenuation.
“0” CD mode
“1” CD-ROM mode
Interpolates the signal based on 588 counter when the frame synchronization signal is not in the window.
This specifies the number of frames.
Selects CD mode or CD-ROM mode.
When an uncorrectable error is detected in the upper or lower 8 bits of audio data (16 bits), it is output
after performing interpolation. High level is output from the FLAG pin at the same time.
Even if an uncorrectable error is detected in the upper or lower 8 bits of CD-ROM data (16 bits), it is
output without performing interpolation. However, the FLAG pin outputs whether an error was
detected in either the upper or the lower 8 bits. This makes highly accurate erasure correction
possible in a CD-ROM system connected to the PD63711.
