Setup Level Setting
When the NTSC operation mode is selected, one of the two kinds of setup level can be selected
by setting of registers.
When the setup level 0 is selected, the Black-to-White is 100IRE.
When the setup level 7.5IRE is selected, the Black-to-White is 92.5IRE.
However, this setup function is valid only for the NTSC mode and invalid for the PAL mode.
Color Bar Generation Function
25%, 50%, 75% or 100% luminance order color bar is output by setting internal registers. The
output timings for each color bar color is as follows.
