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 = 037H
DATA BYTE
LOGIC LEVEL
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
vertical blanking is forced in accordance with CCIR-624 (50 Hz) or RS170A (60 Hz);
note 1
selects the phase reset mode of the colour subcarrier generator; see Table 28
