interrupt
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).
Lock state interrupt
0 = TVP5150AM1 is not locked to the video signal (default).
1 = TVP5150AM1 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.
