Video Port Control Registers
2-25 Video Port SPRU629
Table 2–9. Video Port Interrupt Status Register (VPIS) Field Descriptions (Continued)
Bit Description Value symval field
22 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.
