These are the 8 LSBs of the 11-bit code that sets the horizontal trigger phase related to
the signal on RCV1 or RCV2 input. The 3 MSBs are held in subaddress 6DH;
see Table 53. Values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed.
Increasing HTRIG[10:0] decreases delays of all internally generated timing signals.
Reference mark: analog output horizontal sync (leading slope) coincides with active
edge of RCV used for triggering at HTRIG[10:0] = 4FH (79).
These are the 3 MSBs of the horizontal trigger phase code; see Table 52.
Sets the vertical trigger phase related to signal on RCV1 input. Increasing VTRIG
decreases delays of all internally generated timing signals, measured in half lines;
variation range of VTRIG[4:0] = 0 to 31 (1FH).
0 = vertical blanking is defined by programming of FAL and LAL; default state after reset
1 = vertical blanking is forced in accordance with “ITU-R BT.624” (50 Hz) or RS170A
(60 Hz)
0 = encoder in normal operation mode
1 = output signal is forced to blanking level; default state after reset
These 2 bits select the phase reset mode of the colour subcarrier generator;
see Table 55.
These 2 bits select the delay on luminance path with reference to chrominance path;
see Table 56.
These 2 bits select field length control; see Table 57.
no reset or reset via RTCI from SAA7111 if bit RTCE = 1; default value after reset
reset every two lines or SECAM specific if bit SECAM = 1
reset every eight fields
reset every four fields
