SFDB
Short field detected on channel B interrupt detected bit.
BT.656 or Y/C capture mode – SFDB is set when short field
detection is enabled and VCOUNT is reset before
VCOUNT = YSTOP.
Raw data mode, or TSI capture mode or display mode – Not used.
NONE
0
No interrupt is detected.
CLEAR
1
Interrupt is detected. Bit is cleared.
21
VINTB2
Channel B field 2 vertical interrupt detected bit.
BT.656 or Y/C capture mode – VINTB2 is set when a vertical
interrupt occurred in field 2.
Raw data mode or TSI capture mode – Not used.
NONE
0
No interrupt is detected.
CLEAR
1
Interrupt is detected. Bit is cleared.
20
VINTB1
Channel B field 1 vertical interrupt detected bit.
BT.656 or Y/C capture mode – VINTB1 is set when a vertical
interrupt occurred in field 1.
Raw data mode or TSI capture mode – Not used.
NONE
0
No interrupt is detected.
CLEAR
1
Interrupt is detected. Bit is cleared.
19
SERRB
Channel B synchronization error interrupt detected bit.
BT.656 or Y/C capture mode – Synchronization parity error on
channel B. An SERRB typically requires resetting the channel
(RSTCH) or the port (VPRST).
Raw data mode or TSI capture mode – Not used.
NONE
0
No interrupt is detected.
CLEAR
1
Interrupt is detected. Bit is cleared.
