DATA BYTE
first active line = FAL + 4 for M systems; = FAL + 1 for other systems, measured in lines
last active line = LAL + 3 for M systems; = LAL for other systems, measured in lines
Version identification of the device. It will be changed with all versions of the IC that have different
programming models. Current version is 100 binary.
1 = closed caption bytes of the odd field have been encoded.
0 = the bit is reset after information has been written to the subaddresses 67 and 68. It is set
immediately after the data have been encoded.
1 = closed caption bytes of the even field have been encoded.
0 = the bit is reset after information has been written to the subaddresses 69 and 6A. It is set
immediately after the data have been encoded.
State of the internal field sequence counter.
Bit 0 (FSQ0) gives the odd/even information; odd = LOW, even = HIGH.
SUBADDRESS
FAL = 0 coincides with the first field synchronization pulse
LAL = 0 coincides with the first field synchronization pulse
