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 signal input to the FSTI pin. See the description of $3E for XT1D.

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.

AGGT (LSB)

TE/FE input conversion

DRR2 to DRR0: Partially clears the Data RAM values (0 write).

The following values are cleared when set to 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, FCS servo filter is

forcibly set to gain normal status.

On when set to 1; default = 0

LPAS:

Built-in analog buffer low-current consumption mode

This mode reduces the total analog buffer current consumption for the VC, TE, SE and FE

input analog buffers by using a single operational amplifier.

On when set to 1; default = 0

Note) When using this mode, first check whether each error signal is properly A/D converted

using the SRO1 and SRO0 commands of $3F.

SRO1, SRO0:

These commands are used to output various data externally continuously which have been

specified with the $39 command. (However, D15 (DAC) of $39 must be set to 1.)

Digital output (SOCK, XOLT and SOUT) can be obtained from three specified pins by setting

these commands to 1 respectively. The default is 0, 0. (no readout)

The output pins for each case are shown below.

SOCK

XOLT

SRO1 = 1

SRO0 = 1

(See "Description of Data Readout" on the following page.)

AGHF:

This halves the frequency of the internally generated sine wave during AGC.

FTQ:

The slope of the output during focus search is a quarter of the conventional output slope.

These settings are the same for

both focus auto gain control and

tracking auto gain control.
