83H ( MUTE, 12-bit comparison connection settings)
- MUTE (forced muting)
(note1) Effective at the start left-channel output
data.
85H (option settings)
- RAMS1, RAMS2
- YFLGS, YFCKP
When 1: Outputs are instantaneously muted to
When 0: No muting(note 1)
When 0 and 0 : 16M DRAM (4M×4 bits)×double
When 1 and 0 : 4M DRAM (1M×4 bits)×single
When 0 and 1 : 4M DRAM (1M×4 bits)×double
When 1 and 1 : 16M DRAM (4M×4 bits)×single
When 0 and 0: Sets FLAG6 on the falling edge of
When 0 and 1: Sets FLAG6 on the rising edge of
When 1 and 0: Sets FLAG6 when YFLAG=0
When 1 and 1: Sets FLAG6 when YFLAG=1

- MUTE, YDMUTE relationship
- CMP12 (12-bit comparison connection)
- COMPFB, COMP6B, COMP5B, COMP4B
When all mute inputs are 0, mute is released.
When 1: Performs comparison connection using
When 0: Performs comparison connection using
When 0, 0, 0 and 1: Selects 4-bit compression
When 0, 0, 1 and 0: Selects 5-bit compression
When 1, 0, 0 and 0: Selects full-bit compression
In all other cases: Selects 6-bit compression mode
Changing mode without initializing during opera-
tion is possible.
