Description
Selects the luminance delay in reference to the chrominance
00 = No luma delay
01 = 1LLC luma delay
10 = 2LLC luma delay
11 = 3LLC luma delay
This register is to control the sync. generator
Field length control
00 = Interlaced 312.5 lines/field at 50Hz, 262.5 lines/field at 60Hz
01 = Non interlaced 312 lines @50Hz, 262 lines @60Hz
10 = Non interlaced 313 lines @50Hz, 263 lines @60Hz
11 = Non interlaced 313 lines @50Hz, 263 lines @60Hz
Closed caption enable
00 = Line 21 encoding off
01 = Enables encoding in field 1 (odd).
10 = Enables encoding in field 2 (even).
11 = Enables encoding in both fields.
0 = Disables teletext insertion.
1 = Enables teletext insertion.
Selects the actual line where closed caption or extended data are
encoded.
line = (SCCLN + 4) for M-systems
line = (SCCLN +1) for other systems
Active Display Window Horizontal Start bits 7 to 0
Defines the start of the active TV display portion after the border
color. Values above 1715 (FISE=1) or 1727 (FISE=0) are not
allowed.
Active Display Window Horizontal End bits 7 to 0
Defines the start of the active TV display portion after the border
color. Values above 1715 (FISE=1) or 1727 (FISE=0) are not
allowed.
Active Display Window Horizontal End bits 10 to 8.
Defines the start of the active TV display portion after the border
color. Values above 1715 (FISE=1) or 1727 (FISE=0) are not
allowed.
Active Display Window Horizontal Start bits 10 to 8
Defines the start of the active TV display portion after the border
color. Values above 1715 (FISE=1) or 1727 (FISE=0) are not
allowed.
Start of teletext signal with respect to Horizontal Sync
