Description
Wide screen signalling data
bits 13:11 = Reserved
bits 10:8 = Subtitles
Field sequence detection via RTC
0 = Field sequence as FISE in address 61
1 = Field sequence detection via RTC interface
Color detection via RTC interface
0 = Color detection via RTC disabled
1 = Color detection via RTC enabled
Note: The RTCE bit must be set to 1 to enable this feature.
Starting point of color burst in clk cycles from Hsync
PAL=0x21
NTSC=0x25
Color burst end point in clk cycles from Hsync
PAL = 0x1D
NTSC = 0x1D
Copy guard information bits 7:0
Note: The 14 LSBs of the byte carry the information encoded after
the run-in. The 6 MSBs have to carry the CRCC bits in accordance
with the definition of the CGMS encoding format.
Copy guard information bits 15:8
Note: The 14 LSBs of the byte carry the information encoded after
the run-in. The 6 MSBs have to carry the CRCC bits in accordance
with the definition of the CGMS encoding format.
Copy guard enable
0 = Disabled
1 = Enabled
Copy guard information bits 19:16
Note: The 14 LSBs of the byte carry the information encoded after
the run-in. The 6 MSBs have to carry the CRCC bits in accordance
with the definition of the CGMS encoding format.
DAC3 control
0 = Video dac 3 carries the green channel.
1 = Video dac 3 carries the luminance channel.
