DATA BYTE
DESCRIPTION
ADWHS
active display window horizontal start; defines the start of the active TV display portion after the border
colour
values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed
ADWHE
active display window horizontal end; defines the end of the active TV display portion before the
border colour
values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed
Table 60 Subaddress 73H
DATA BYTE
DESCRIPTION
TTXHS
start of signal TTXRQ on pin TTXRQ_XCLKO2 (CLK2EN = 0);
see Fig.14
REMARKS
TTXHS = 42H; is default after
reset if strapped to PAL
TTXHS = 54H; is default after
reset if strapped to NTSC
Table 61 Subaddress 74H
DATA BYTE
DESCRIPTION
REMARKS
TTXHD
indicates the delay in clock cycles between rising edge of TTXRQ
minimum value: TTXHD = 2;
output signal on pin TTXRQ_XCLKO2 (CLK2EN = 0) and valid data at is default after reset
pin TTX_SRES

advanced composite sync against RGB output from 0 XTAL clocks to 31 XTAL clocks
Table 63 Subaddresses 76H, 77H and 7CH
DATA BYTE
DESCRIPTION
TTXOVS
first line of occurrence of signal TTXRQ on pin TTXRQ_XCLKO2
(CLK2EN = 0) in odd field
line = (TTXOVS + 4) for M-systems
line = (TTXOVS + 1) for other systems
TTXOVE
last line of occurrence of signal TTXRQ on pin TTXRQ_XCLKO2
(CLK2EN = 0) in odd field
line = (TTXOVE + 3) for M-systems
line = TTXOVE for other systems
REMARKS
TTXOVS = 05H; is default
after reset if strapped to PAL
TTXOVS = 06H; is default
after reset if strapped to
NTSC
TTXOVE = 16H; is default
after reset if strapped to PAL
TTXOVE = 10H; is default
after reset if strapped to
NTSC
