DATA BYTE
DESCRIPTION
HTRIG
sets the horizontal trigger phase related to signal on RCV1 or RCV2 input (or to decoded “CCIR 656”
data)
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 = tbfH (tbfH)
DATA BYTE
DESCRIPTION
VTRIG
sets the vertical trigger phase related to signal on RCV1 input (or to decoded “CCIR 656”data)
increasing VTRIG decreases delays of all internally generated timing signals, measured in half lines
variation range of VTRIG = 0 to 31 (1FH)

DESCRIPTION

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 23
field length control; see Table 24
