XT4D, XT2D:
MCK (digital servo master clock) frequency division setting
This command forcibly sets the frequency division ratio to 1/4, 1/2 or 1/1 when MCK is
generated from the FSTIO pin clock. See the description of $3E for XT1D. And see "§ 4-12.
Clock System".
AGG4:
This varies the amplitude of the internally generated sine wave using the AGGF and AGGT
commands during AGC. When AGG4 = 0, the default is used. When AGG4 = 1, the setting is
as shown in the table below.

DRR2 to DRR0
: Partially clears the Data RAM values (0 write).
The following values are cleared when 1 (on) respectively; default = 0
DRR2: M08, M09, M0A
DRR1: M00, M01, M02
DRR0: M00, M01, M02 only when LOCK = low
Note)
Set DRR1 and DRR0 on for 50μs or more.
ASFG:
When vibration detection is performed during anti-shock circuit operation, the FCS servo filter
is forcibly set to gain normal status.
On when 1; default is 0
FTQ:
The focus search-up speed is set to the 1/4 value of that determined by FT1, FT0 and FTZ ($35).
On when 1; default is 0
See $37 for AGGF and AGGT.
The presets are AGG4 = 0,
AGGF = 1 and AGGT = 1.
