Bits
BWB7 — BWB0
(bit7 — 0)
Description
B channel cut-off control.
The cut-off adjustment B used to adjust the raster white balance.
CUT7 — CUT0 The cut-off brightness adjustment is made by simultaneously controlling
(bit7 — 0)
the external cut-off current.
HT
(bit 0)
HS3 — HS1
(bit3 — 1)
Video & OSD half tone enable.
If you set this bit to ’1’, the half tone function is on.
Then you can see the video signal & OSD raster.
HS3 — HS1 bits select OSD raster color 1 to be half tone.
To carry out half tone function, set the HT bit to ’1’.
