DESCRIPTION
7 to 0
HTRIG[7:0]
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).

SBLBN
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.
