SETUP LEVEL SETTING

When the NTSC operation mode is selected, one of the two kinds of setup level can be selected

by setting of internal register (MR1[7]).

When the setup level 0IRE (MR1[7] = "0") is selected, the Black-to-White is 100IRE.

When the setup level 7.5IRE (MR1[7] = "1") 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

The 25% luminance order color bar or 50% luminance order color bar or 75% luminance order

color bar or 100% luminance order color bar is output by setting internal register CR0[2:1]. The

output timings for each color bar color are as follows.
