LLAOM LLAIM LLBAM LLAG4 LLAG3 LLAG2 LLAG1 LLAG0
LLAG4-LLAG0 Left LINE Alternate Volume. This
register is used to control the LLINE
analog input volume to the mixers
when I18 is remapped to control FM
and/or Wavetable Serial Port vol-
ume. The remapping bits are FMRM
and WTRMD (X4). The least signifi-
cant bit represents 1.5 dB, with
01000 = 0 dB. See Table 10.
LLABM
Left LINE Alternate Bypass Mute.
When set to 1, the analog Left Line
Input, LLINE, (bypassing the gain
block) to the input mixer is muted.
LLAIM
Left LINE Alternate Input Mute.
When set to 1, the Left Line Input,
LLINE, from the volume control to
the input mixer is muted.
LAOM
Left LINE Alternate Output Mute.
When set to 1, the Left Line Input,
LLINE, from the volume control to
the output mixer is muted.

RLAG4-RLAG0 Right LINE Alternate Volume.
This register is used to control the
RLINE analog input volume to the
mixers when I19 is remapped to con-
trol FM and/or Wavetable Serial Port
volume. The remapping bits are
FMRM and WTRMD in X4. The
least significant bit represents
1.5 dB, with 01000 = 0 dB.
See Table 10.
RLABM
Right LINE Alternate Bypass Mute.
When set to 1, the analog Right Line
Input, RLINE, (bypassing the gain
block) to the input mixer is muted.
RLAIM
Right LINE Alternate Input Mute.
When set to 1, the Right Line Input,
RLINE, from the volume control to
the input mixer is muted.
RLAOM
RLINE
(Synthesis)
Right LINE Alternate Output Mute.
When set to 1, the Right Line Input,
