Genlock Loss
Interrupt Mask
If this bit is a “1”, an interrupt is generated when genlock is lost.
0 = Interrupt disabled
1 = Interrupt enabled

Input Signal Loss
Interrupt Mask
If this bit is a “1”, an interrupt is generated when a video signal is no longer detected on
the selected video input.
0 = Interrupt disabled
1 = Interrupt enabled

Closed Caption
Interrupt Mask
If this bit is a “1”, an interrupt is generated when the Caption_ODD_A and
Caption_ODD_B or the Caption_EVEN_A and Caption_EVEN_B data registers contain
new data.
0 = Interrupt disabled
1 = Interrupt enabled
0

WSS
Interrupt Mask
If this bit is a “1”, an interrupt is generated when the WSS_ODD_A and WSS_ODD_B or
the WSS_EVEN_A and WSS_EVEN_B data registers contain new data.
0 = Interrupt disabled
1 = Interrupt enabled
0

Teletext
Interrupt Mask
If this bit is a “1”, an interrupt is generated when teletext information is first detected at
the beginning of each field.
0 = Interrupt disabled
1 = Interrupt enabled

Genlock Loss
Interrupt Status
If this bit is a “1”, the reason for the interrupt request was that genlock was lost. To clear
the interrupt request, a “1” must be written to this bit.

Input Signal Loss
Interrupt Status
If this bit is a “1”, the reason for the interrupt request was that the input video source is
no longer present. To clear the interrupt request, a “1” must be written to this bit.

Teletext
Interrupt Status
If this bit is a “1”, the reason for the interrupt request was that teletext data has been de-
tected in the current field. To clear the interrupt request, a “1” must be written to this bit.
