 Detects disconnection/short circuit of BCLK.

Set the "Detects disconnection/short circuit of BCLK" with the BCKEN bit of the SAFE command.

When the BCLK is stopped, the error bit (BCKERR) is set to "1".

Error bit (BCKERR) can be read with RDERR command. Also, error bit (BCKERR) can be cleared by ERRCL command.

*1 Set BCKEN = "1"

*2 Set BCKEN = "0"

*3 Misoperation detection and failure detection outputs are selected by OUTSTAT command.

*4 Set OUTEN = "1" or INEN = "1"

 Detects disconnection/short circuit of LRCLK.

Set the "Detects disconnection/short circuit of LRCLK" with the LRCKEN bit of the SAFE command.

When the LRCLK is stopped, the error bit (LRCKERR) is set to "1".

Error bit (LRCKERR) can be read with RDERR command. Also,error bit (LRCKERR) can be cleared by ERRCL command.

*1 Set LRCKEN = "1"

*2 Set LRCKEN = "0"

*3 Misoperation detection and failure detection outputs are selected by OUTSTAT command.

*4 Set OUTEN = "1" or INEN = "1"

< When SAFE command LRCKEN bit is "0" >

Disconnection or short circuit of LRCLK is not detected.

When LRCLK is faster than 5%, SAICH is initialized and the recorder stops playing.*5 At that time, the error bit

(LRCKERR) keeps "0".

< When SAFE command LRCKEN bit is "1" >

Disconnection or short circuit of LRCLK is detected.

When LRCLK is faster than 5%, SAICH is initialized and the recorder stops playing.*5 At that time, the error bit

(LRCKERR) changes "1".

*5 : The unit does not recover even if a normal LRCLK is input after stopping playback. Enter MUON command →

SAICH command after inputting a normal LRCLK.
