4-0 TGSHLD[4:0]
CCD TG shoulder width (in pixel time). Please refer to Reg34.
Note: Designers have to program the TGSHLD >= 2 (more than two).
0 Clock 4 will be high when TG goes high.
1 Clock 4 will be low when TG goes high.
0 Clock 3 will be high when TG goes high.
1 Clock 3 will be low when TG goes high.
0 Clock 1 & 2 will be high when TG goes high.
1 Clock 1 & 2 will be low when TG goes high.

7-4 WDTIME[3:0]
To set watch-dog time.
3-0 LINESEL[3:0]
To set vertical resolution for CIS or dummy lines for CCD.
CIS : LINESEL = 0 full resolution.
The unit is 30 seconds.
= 1 1/2 resolution.
= 2 1/3 resolution .
…
..
= 15 1/16 resolution.
CCD : LINESEL = 0 no dummy line.
= 1 1 dummy line.
= 2 2 dummy lines.
…
..
= 15 15 dummy lines.
Note: In contrary to dummy line feature in CCD, for low resolution in CIS, the
scanning speed is improved by implementing fast motor moving.

To set buffer condition.
When buffer is full, scanner will stop and wait for host to read out image data
from SDRAM.
The valid data count (has not been read) is represented by VALIDWORD (in word).
