Filter logic
Mode
TTX filter 2 enable
TTX filter 1 enable
Filter logic: Allows different logic to be applied when combining the decision of filter 1 and filter 2 as follows:
00 = NOR (default)
01 = NAND
10 = OR
11 = AND
Mode:
0 = Teletext WST PAL mode B (2 header bytes) (default)
1 = Teletext NABTS NTSC mode C (5 header bytes)
TTX filter 2 enable:
0 = Disabled (default)
1 = Enabled
TTX filter 1 enable:
0 = Disabled (default)
1 = Enabled
If the filter matches or if the filter mask is all 0s, a true result is returned.

Lock state interrupt
Lock interrupt

FIFO threshold interrupt
Line interrupt
Data interrupt
Lock state interrupt:
0 = TVP5154 is not locked to the video signal (default)
1 = TVP5154 is locked to the video signal.
Lock interrupt:
0 = A transition has not occurred on the lock signal (default).
1 = A transition has occurred on the lock signal.
FIFO threshold interrupt:
0 = The amount of data in the FIFO has not yet crossed the threshold programmed at address C8h (default).
1 = The amount of data in the FIFO has crossed the threshold programmed at address C8h.
Line interrupt:
0 = The video line number has not yet been reached (default).
1 = The video line number programmed in address CAh has occurred.
Data interrupt:
0 = No data is available (default).
1 = VBI data is available either in the FIFO or in the VBI data registers.
The interrupt status register A can be polled by the host processor to determine the source of an interrupt.
After an interrupt condition is set it can be reset by writing to this register with a 1 in the appropriate bit(s).
