Example: 1080I/P
THS8200/10 is put into 1080I mode by programming ‘dtg1_mode’ = ‘0001’. The figure below shows the required
output format of both fields for 1080I and 1080P.
When in 1080I preset mode, the (linetype,breakpoint) table, and frame & field size registers are filled out as follows
internally:

From line 1 to 5, linetype BTSP_BTSP will be generated. When the linecounter reaches line#6, the DTG will switch
to linetype NTSP_NTSP, etc. Note that the ‘dtg1_spec_<x>’ registers need to be filled out with the correct values to
set the horizontal line timings.
