Macrovision detect changed
0 = Macrovision detect status has not changed.
1 = Macrovision detect status has changed.
Field rate changed
0 = Field rate has not changed.
1 = Field rate has changed.
Line alternation changed
0 = Line alteration has not changed.
1 = Line alternation has changed.
Color lock changed
0 = Color lock status has not changed.
1 = Color lock status has changed.
H/V lock changed
0 = H/V lock status has not changed.
1 = H/V lock status has changed.
TV/VCR changed
0 = TV/VCR status has not changed.
1 = TV/VCR status has changed.
Interrupt status register B is polled by the external processor to determine the interrupt source for interrupt
B. After an interrupt condition is set, it can be reset by writing to the interrupt reset register B at
subaddress 1Ch with a 1 in the appropriate bit.
