◆SAICH command

[ ] Set these bits when channels other than SAIs are not playing back (BUSYBn is "1").

[ ] If you want to set LEN="0" and REN="1" with LEN="1" and REN="0", set LEN="0" and REN="1" after setting

LEN=REN="0".

[ ] Start the LRCLK/BCLK input after entering the SAICON command.Subsequently, enter the MUON command and

then the SAICH command.

[ ] After entering the MUON command, enter the SAICH command at least 10ms prior to the end of the silence period set

by the MUON command.

[ ] Use a channel that is not played back by SAICH as the playback channel set by MUON commands. To mix with ROM

playback, use a channel for ROM playback.

◆SAICON command

[ ] Set this bit when the Lch-side serial audio interface (SAI) operation of the SAICH command is stopped (LEN="0") and

the Rch-side serial audio interface (SAI) operation is stopped (REN="0"). If either LEN or REN is set to "1", the

entered SAICON command is ignored.

◆SAITCON command

[ ] Use the same format as that of SAIRCON command. Set this bit when the Lch-side serial audio interface (SAI)

operation of the SAICH command is stopped (LEN="0") and the Rch-side serial audio interface (SAI) operation is

stopped (REN="0"). If either LEN or REN is set to "1", the entered SAITCON command is ignored.

◆SAIRCON command

[ ] Use the same format as that of SAITCON command. Set this bit when the Lch-side serial audio interface (SAI)

operation of the SAICH command is stopped (LEN="0") and the Rch-side serial audio interface (SAI) operation is

stopped (REN="0"). If either LEN or REN is set to "1", the entered SAIRCON command is ignored.

◆SAIMOD command

[ ] Set this bit when the Lch-side serial audio interface (SAI) operation of the SAICH command is stopped (LEN="0") and

the Rch-side serial audio interface (SAI) operation is stopped (REN="0"). If either LEN or REN is set to "1", the

entered SAIMOD command is ignored.
