FUNCTION
SRCV11
SRCV10
0
VS
vertical sync each eld; default after reset
0
1
FS
frame sync (odd/even)
1
0
FSEQ
eld sequence, vertical sync every fourth eld
(PAL = 0) or eighth eld (PAL = 1)
1
not applicable
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)
DATA BYTE
LOGIC
LEVEL
DESCRIPTION
SBLBN
0
vertical blanking is dened by programming of FAL and LAL; default after reset
1
vertical blanking is forced in accordance with
“CCIR 624” (50 Hz) or RS170A (60 Hz)
PHRES
selects the phase reset mode of the colour subcarrier generator; see Table 29
FLC
eld length control; see Table 30
DATA BYTE
DESCRIPTION
PHRES1
PHRES0
0
no reset or reset via RTCI from SAA7111 if bit RTCE = 1; default after reset
0
1
reset every two lines
1
0
reset every eight elds
1
reset every four elds
