Programming registers are Reg5B/5C/5D/5E.

B6 : TCDFAST :reserved.

B5 : DMYPIX

:reserved.

B4~0 :TGSHLD[4:0] : to set CCD TG shoulder width.

7.22. Reg : 1EH (Write)

Defalut : 20H

B7~4:WDTIME[3:0] : to set watch-dog time.

Time : fast mode : WDTIME*2*(16K)*(Line-Priod).

normal mode: WDTIME*(16K)*(Line-Priod).

B3~0:LINESEL[3:0] : to set CIS Vertical DPI or dummy lines.

CIS : LINESEL =0 full dpi.

=1 1/2 dpi

=2 1/3 dpi

=3 1/4 dpi

…..

=15 1/16 dpi

CCD : LINESEL=0 no dummy line.

=1 1 dummy line.

=2 2 dummy lines.

=3 3 dummy lines.

……

=15 15 dummy lines.

Note : CIS can be implemented dummy line by motor move method, not dummy lines.

7.23. Reg : 1FH (Write)

Default : 00H

SCANFED[7:0]: move to scanning position by table one.

7.24. Reg : 20H (Write)

Default : 00H

BUFSEL[7:0] : to set buffer condition (unit = 2k word).

Scanner execute backward/forward moving whenever buffer full.

If MAXWD < buffer condition, then motor move forward to scan.

7.25. Reg : 21H (Write)

Defalut : 00H

STEPNO[7:0]: to set table one steps number for forward slope curve of the acceleration/deceleration.

7.26. Reg : 22H (Write)

Defalut : 00H

FWDSTEP[7:0] : to set steps number of the forward steps.

7.27. Reg : 23H (Write)

Defalut : 00H

BWDSTEP[7:0] : to set steps number of the backward steps.

7.28. Reg : 24H (Write)

Defalut : 00H

FASTNO[7:0]: to set table one steps number for backward slope curve of the acceleration/deceleration under scanning
