bit 2 : DAMIXEN (digital audio mixer enable)
High : Attenuator and mixer are not activated for CD-DA.
Low : Attenuator and mixer are activated for CD-DA.
bit 1 : DACODIS (DAC out disable)
High : Clock signals are output from the WCKO, LRCO and BCKO pins even for muting.
Low : The WCKO, LRCO and BCKO pins are set low for muting.
bit 0 : Reserved
Normally fixed low.
2-1-4. DECCTL (decoder control) register
bit 7 : ENDLADR (enable drive last address)
High : DLADR (drive last address) is enabled when this is high. When DADRC and DLADR become
equal while the decoder is in the write-only, real-time correction or CD-DA mode, the data writing
from the driver into the buffer is stopped.
Low : DLADR (drive last address) is disabled when this is low. Even when DADRC and DLADR become
equal while the decoder is in the write-only, real-time correction or CD-DA mode, data writing from
the driver into the buffer is not stopped.
bit 6 : ECCSTR (ECC strategy)
High : Errors are corrected with consideration given to the error flags of the data.
Low : Errors are corrected with no consideration given to the error flags of the data. In this case, there is
no erasure correction. Set this bit low when the IC is connected to an 8-bit/word SRAM.
bit 5 : MODESEL (mode select)
bit 4 : FORMSEL (form select)
When AUTODIST is low, the sector is corrected in the MODE or FORM indicated below.

“L”
“H”

bit3
: AUTODIST (auto distinction)
High : Errors are corrected according to the MODE byte and FORM bit read from the drive.
Low : Errors are corrected according to the MODESEL and FORMSEL bits (bits 5 and 4).
bits 2 to 0 : DECMD2 to 0 (decoder mode 2 to 0)

When the CD-DA bit (bit 4) in the CHPCTL register is to be set high, set the decoder to the disable
or CD-DA mode.
