with 0. ”Duration” is a 10-bit value representing the number of clock cycles. “Select”
indicates whether the value is actually inserted into the video data stream or not.
“Value index” is a 3-bit index into the next table in the linked list called “Value array.”
Certain bits of the “value index” can also be used to generate a digital sync raster
provided at the H- and V-sync outputs of the PNX8510/11.
“Value array” can hold up to 8 values (counted from 0 though 7) which are 10-bit
signed 2’s complement.
7.2.2
Trigger generation
To ease the trigger setup for the sync generation module, a set of registers is
provided to set up the screen raster defined as width and height. A trigger position
can be specified as an x, y coordinate within the overall dimensions of the screen
raster. If the x, y counter matches the specified coordinates, a trigger pulse is
generated which pre-loads the tables with their initial values. Refer to the 1080i
example for the trigger programming.
Important Notes
The “duration” in the “Line_Pattern_Array” that needs to be programmed should be
1 cycle less than the actual duration required.
For the registers LCNT_ARRAY_ADR (offset 0x82), LTYPE_ARRAY_ADR (offset
0x86), LPATT_ARRAY_ADR (offset 0x8E), “addr+1” should be written to finish
writing the data meant for “addr,” for example:

Note the next address, 0x02, is written to finish writing to the previous address 0x01.

LTYPE_ARRAY_LINE2 = 0x03
