Data input from the LRCKI, BCKI, and DATAI pins
The source signal for the zero detection D/A converter muting circuit can be switched as shown below by the XDSEL
flag in the HDCD control register.

HDCD block functions
— Automatic discrimination of HDCD encoded discs
— PE, GS, and LLE processing (HDCD decoder block)
— HDCD and GAIN signal output

oversampling HDCD filters, deemphasis, and attenuation (HDCD filter block)
— Output of HDCD decoded signals to the digital interface block
— Output of HDCD decoded signals to LRCKO, DACKO, and DFOLO
— Output of HDCD filtered signals from LRCKO, DACKO, DFOLO, and DFORO
— Output of HDCD filtered signals to the D/A converter block
— HDCD filter block source signal switching
When data with value other than zero is input as a source signal, the mute detection circuit immediately turns off and
the MUTEL or MUTER pin returns to the low level.
