SYCOF
When LRCK, PCMD and BCK are connected directly with LRCKI, PCMDI and BCKI, respectively, playback
can be performed easily in CAV-W mode by setting SYCOF of address 9 to 1.
Normally, the memory proof, etc., is used for playback in CAV-W mode.
In CAV-W mode, the LRCK output conforms not to the crystal but to the VCO. Therefore, synchronization is
frequently lost.
Setting SYCOF of address 9 to 1 ignores the LRCKI's asynchronization, facilitating playback. However, the
playback is not perfect because pre-value hold or data skip occurs due to the wow and flutter in the LRCKI
input.
Set SYCOF to 0 other than when connecting LRCK, PCMD and BCK directly with LRCKI, PCMDI and
BCKI, respectively, and performing playback in CAV-W mode.
Digital Bass Boost
Bass boost without external parts is possible using the built-in digital filter. The boost strength has two levels:
MID and MAX.
The bass boost is set using BSBST and BBSL of address A.
See Graph 4-15 for the digital bass boost frequency response.
