GL646USB
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
