DATA BYTE
DESCRIPTION
HTRIG
sets the horizontal trigger phase related to signal on RCV1 or RCV2 input
values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed; increasing HTRIG 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 = 398H (398H)
DATA BYTE
DESCRIPTION
VTRIG
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 = 0 to 31 (1FH)

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)
selects the phase reset mode of the colour subcarrier generator; see Table 28
field length control; see Table 29
