Description
0 = DACs for R, G and B in normal operational mode,
1 = DACs for R, G and B forced to lowest output voltage; default state
after reset.
0 = DACs for CVBS, Y and C in normal operational mode; default state
after reset,
1 = DACs for CVBS, Y and C forced to lowest output voltage.
0 = PAL switch phase is nominal; default state after reset,
1 = PAL switch phase is inverted compared to nominal if RTC is enabled;
see
0 = luminance gain for white
1 = luminance gain for white
black.
0 = no SECAM encoding; default state after reset,
1 = SECAM encoding activated; bit PAL has to be set to logic 0.

Description
these 2 bits select the cross-color reduction filter in luminance;
see
these 6 bits select the variable blanking level during vertical blanking;
interval is typically identical to value of BLNNL
Description
