F1NM, F1DM: Quasi double accuracy setting for FCS servo filter first-stage
On when 1; default is 0.
F1NM: Gain normal
F1DM: Gain down
T1NM, T1UM: Quasi double accuracy setting for TRK servo filter first-stage
On when 1; default is 0.
T1NM: Gain normal
T1UM: Gain up
F3NM, F3DM: Quasi double accuracy setting for FCS servo filter third-stage
On when 1; default is 0.
Generally, the advance amount of the phase increases by partially setting the FCS servo third-
stage filter which is used as the phase compensation filter to double accuracy.
F3NM: Gain normal
F3DM: Gain down
T3NM, T3UM: Quasi double accuracy setting for TRK servo filter third-stage
On when 1; default is 0.
Generally, the advance amount of the phase increases by partially setting the TRK servo third-
stage filter which is used as the phase compensation filter to double accuracy.
T3NM: Gain normal
T3UM: Gain up
Note) Filter first- and third-stage quasi double accuracy settings can be set individually.
See "§5-20 Filter Composition" at the end of this specification concerning quasi double accuracy.
DFIS:

COIN:
This command masks the TLC2 command set by D2 of $38 only when FOK is low.
On when 1; default is 0
When 0, the internally generated LOCK signal is output to the LOCK pin. (default)
When 1, the LOCK signal can be input from an external source to the LOCK pin.
When 0, the internally generated COUT signal is output to the COUT pin. (default)
When 1, the COUT signal can be input from an external source to the COUT pin.
The MIRR, DFCT and FOK signals can also be input from an external source.
MDFI:
When 0, the MIRR, DFCT and FOK signals are generated internally. (default)
When 1, the MIRR, DFCT and FOK signals can be input from an external source through the
MIRR, DFCT and FOK pins.
MIRI:
When 0, the MIRR signal is generated internally. (default)
When 1, the MIRR signal can be input from an external source through the MIRR pin.

MIRR, DFCT and FOK are all generated internally.
MIRR only is input from an external source.
MIRR, DFCT and FOK are all input from an external source.

XT1D:
The input to the servo master clock is used without being frequency-divided by setting XT1D to 1.
This command takes precedence over the XTSL pin, XT2D and XT4D. See the description of $3F
for XT2D and XT4D.
