85H (option settings)
- RAMX2
When 1: Uses 2 DRAMs (use external DRAM)
When 0: Uses a single DRAM (internal only)
- YFLGS, YFCKP
When 0 and 0: Sets FLAG6 on the falling edge of
YFCLK when YFLAG=0
When 0 and 1: Sets FLAG6 on the rising edge of
YFCLK when YFLAG=0
When 1 and 0: Sets FLAG6 when YFLAG=0
When 1 and 1: Sets FLAG6 when YFLAG=1
- COMPFB, COMP6B, COMP5B, COMP4B
When 0, 0, 0 and 1: Selects 4-bit compression
mode
When 0, 0, 1 and 0: Selects 5-bit compression
mode
When 1, 0, 0 and 0: Selects full-bit compression
mode
In all other cases: Selects 6-bit compression mode
Changing mode without initializing during opera-
tion is possible.
83H (ATT, MUTE, 12-bit comparison connection settings)
- ATT (attenuator enable)
When 1: Attenuator settings become active (84H
command)
When 0: Attenuator settings become inactive, and
output continues without attenuation
- MUTE (forced muting)
When 1: Outputs are instantaneously muted to
0.(note 1)
Same effect as taking the YDMUTE pin
HIGH.
When 0: No muting(note 1)
(note1) Effective at the start of left-channel output
data.
- SOFT (soft muting)
When 1: Outputs are smoothly muted to 0.
When 0: No muting.
Soft mute release occurs instantaneously
to either the value set by the 84H com-
mand (When ATT=1) or 0dB (When
ATT=0)
- MUTE, SOFT, YDMUTE relationship
When all mute inputs are 0, mute is released.
- NS (noise shaper enable)
When 1: Includes noise shaper function in com-
pression-mode shockproof operation.
When 0: Performs comparison connection using
all 16 bits of input data.
- CMP12 (12-bit comparison connection)
When 1: Performs comparison connection using
only the most significant 12 bits of input
data.
When 0: Performs comparison connection using
all 16 bits of input data.
