VIP_INT Bit Descriptions
Bit Name Description
31:16 INT_STATUS VIP Interrupt Status.
0: INT not pending.
1: INT pending.
Writing a 1 to this bit clears the status.
Bit 30: FIFO line wrap error.
Bit 29: FIFO overflow error.
Bit 28: FIFO threshold hit.
Bit 27: Long line (> 3000 clocks) error.
Bit 26: Vertical timing error (frame error or address error)/Msg missed error.
Bit 25: Active pixels per line error.
Bit 24: VIP clock input error.
Bit 23: Ancillary checksum or parity error.
Bit 22: Msg buffer full or ancillary threshold packet count reached.
Bit 21: End of vertical blanking.
Bit 20: Start of vertical blanking.
Bit 19: Start of even field.
Bit 18: Start of odd field.
Bit 17: Current line = VIP Line Target (see Current/Target Line register).
Bit 16: Not used (0).
15:0 INT_MASK VIP Interrupt Masks.
0: Enable, unmask the INT.
1: Disabled, mask the INT.
Bit 14: When enabled (0), allows FIFO line wrap error INT.
Bit 13: When enabled (0), allows FIFO overflow error INT.
Bit 12: When enabled (0), allows FIFO threshold hit INT.

Bit 9: When enabled (0), allows the active pixel input video error INT.
Bit 8: When enabled (0),allows the VIP clock input error INT.
Bit 7: When enabled (0), allows ancillary checksum or parity error INT.
Bit 6: When enabled (0), allows msg buffer full INT or ancillary threshold packet count
reached INT.
Bit 5: When enabled (0), allows end of vertical blanking INT.
Bit 4: When enabled (0), allows start of vertical blanking INT.
Bit 3: When enabled (0), allows start of even field INT.
Bit 2: When enabled (0), allows start of odd field INT.
