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
chrominance SCH phases based on the standard input video format. VCR mode is determined by
detecting variations in the chrominance SCH phases compared to the chrominance SCH phases of the
standard input video format.
0 = TV
1 = VCR
