864 total pixel clocks per line; default after reset
858 total pixel clocks per line
NTSC encoding (non-alternating V component)
PAL encoding (alternating V component); default after reset
enlarged bandwidth for chrominance encoding (for overall transfer characteristic of
chrominance in baseband representation see Figs 3 and 4)
standard bandwidth for chrominance encoding (for overall transfer characteristic of
chrominance in baseband representation see Figs 3 and 4); default after reset

luminance gain for white
PAL switch phase is nominal; default after reset
PAL switch phase is inverted compared to nominal if RTC is enabled (see Table 23)
DAC for CVBS in normal operational mode; default after reset
DAC for CVBS forced to lowest output voltage
DACs for R, G and B in normal operational mode
DACs for R, G and B forced to lowest output voltage; default after reset
no real-time control of generated subcarrier frequency; default after reset
real-time control of generated subcarrier frequency through SAA7151B or SAA7111; for
timing see Fig.13
