DATA BYTE
DESCRIPTION
TTXHS
TTXHD
start of signal on pin TTXRQ see Fig.7
indicates the delay in clock cycles between rising edge of TTXRQ output and valid data on pin TTX
minimum value has to be TTXHD = 2
DATA BYTE
DESCRIPTION
VS_S
Vertical Sync. shift between RCV1 and RCV2 (switched to output) in master mode it is possible to shift
H-sync (RCV2; CBLF = 0) against V-sync (RCV1; SRCV1 = 00)
standard value: VS_S = 3
DATA BYTE
DESCRIPTION
TTXOVS
first line of occurrence of signal on pin TTXRQ in odd field
line = (TTXOVS + 4) for M-systems
line = (TTXOVS + 1) for other systems
last line of occurrence of signal on pin TTXRQ in odd field
line = (TTXOVE + 3) for M-systems
line = TTXOVE for other systems
TTXOVE
DATA BYTE
DESCRIPTION
TTXEVS
first line of occurrence of signal on pin TTXRQ in even field
line = (TTXEVS + 4) for M-systems
line = (TTXEVS + 1) for other systems
last line of occurrence of signal on pin TTXRQ in even field
line = (TTXEVE + 3) for M-systems
line = TTXEVE for other systems
TTXEVE
DATA BYTE
LOGIC
LEVEL
DESCRIPTION
TTX60
0
1
enables NABTS (FISE = 1) or European TTX (FISE = 0); default after reset
enables World Standard Teletext 60 Hz (FISE = 1)
DATA BYTE
DESCRIPTION
FAL
first active line = FAL + 4 for M-systems, = FAL + 1 for other systems, measured in lines FAL = 0
coincides with the first field synchronization pulse
last active line = LAL + 3 for M-systems, = LAL for other system, measured in lines LAL = 0 coincides
with the first field synchronization pulse
