vertical blanking is defined by programming of FAL and LAL; default after reset
vertical blanking is forced in accordance with “CCIR 624” (50 Hz) or RS170A (60 Hz)
encoder in normal operation mode
output signal is forced to blanking level; default after reset
selects the phase reset mode of the colour subcarrier generator; see Table 32
selects the delay on luminance path with reference to chrominance path; see Table 33
field length control; see Table 34
no reset or reset via RTCI from SAA7111 if bit RTCE = 1; default after reset
reset every two lines
reset every eight fields
reset every four fields
no luminance delay; default after reset
1 LLC luminance delay
2 LLC luminance delay
3 LLC luminance delay
interlaced 312.5 lines/field at 50 Hz, 262.5 lines/field at 60 Hz; default after reset
non-interlaced 312 lines/field at 50 Hz, 262 lines/field at 60 Hz
