Interrupt B
Interrupt B:
0 = Interrupt B is not active on the external terminal (default).
1 = Interrupt B is active on the external terminal.
The interrupt active register B is polled by the external processor to determine if interrupt B is active.

Peak white detect status:
0 = Peak white is not detected.
1 = Peak white is detected.
Line–alternating status:
0 = Nonline alternating
1 = Line alternating
Field rate status:
0 = 60 Hz
1 = 50 Hz
Lost lock detect:
0 = No lost lock since status register #1 was last read
1 = Lost lock since status register #1 was last read
Color subcarrier lock status:
0 = Color subcarrier is not locked.
1 = Color subcarrier is locked.
Vertical sync lock status:
0 = Vertical sync is not locked.
1 = Vertical sync is locked.
Horizontal sync lock status:
0 = Horizontal sync is not locked.
1 = Horizontal sync is locked.
TV/VCR status. TV mode is determined by detecting standard line-to-line variations and specific chroma SCH phases based on the
standard input video format. VCR mode is determined by detecting variations in the chroma SCH phases compared to the chroma SCH
phases of the standard input video format.
0 = TV
1 = VCR
