$3E (preset: $3E 00 00)
F1NM, F1DM:
Quasi double accuracy setting for FCS servo filter first-stage
On when 1; default when 0.
F1NM: Gain normal
F1DM: Gain down
T1NM, T1UM:
Quasi double accuracy setting for TRK servo filter first-stage
On when 1; default when 0.
T1NM: Gain normal
T1UM: Gain up
F3NM, F3DM:
Quasi double accuracy setting for FCS servo filter third-stage
On when 1; default when 0.
Generally, the advance amount of the phase becomes large 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 when 0.
Generally, the advance amount of the phase becomes large 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:
FCS hold filter input extraction node selection
0: M05 (Data RAM address 05); default
1: M04 (Data RAM address 04)
TLCD:
This command masks the TLC2 command set by D2 of $38 only when FOK is low.
On when 1; default when 0
LKIN:
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.
COIN:
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.

XT1D:
When XT1D = 1, the input to the servo master clock can be used without dividing its
frequency. This command takes precedence over the XTSL pin, XT2D and XT4D. See the
description of $3F for XT2D and XT4D.
