High-Definition Video Processing Subsystem (HDVPSS)
describes each of the interrupts supported by the VIP Parser.
Table 1-64. VIP Parser Interrupts
Interrupt
Description
PrtBDisableComplete
When Port B is disabled in the middle of the frame, this interrupt is activated
when complete frame is sent out of Port B following disable.
PrtADisableComplete
When Port A is disabled in the middle of the frame, this interrupt is activated
when complete frame is sent out of Port A following disable.
PrtBANCProtocolVio
This interrupt is enabled when the protocol checker on the output of the
dss_vip_parser encounters a violation on the Ancillary VPI of Port B.
PrtBYUVProtocolVio
This interrupt is enabled when the protocol checker on the output of the
dss_vip_parser encounters a violation on the Active Video VPI of Port B.
PrtAANCProtocolVio
This interrupt is enabled when the protocol checker on the output of the
dss_vip_parser encounters a violation on the Ancillary VPI of Port A.
PrtAYUVProtocolVio
This interrupt is enabled when the protocol checker on the output of the
dss_vip_parser encounters a violation on the Active Video VPI of Port A.
PrtBSrc0Size
The output size for Srcnum=0 on Port B differs from the SRC0_NUMLINES
and SRC0_NUMPIX register settings
PrtASrc0Size
The output size for Srcnum=0 on Port A differs from the SRC0_NUMLINES
and SRC0_NUMPIX register settings
PrtBDisConn

PrtAVdet
Video Detect Interrupt for Port A
•
A ‘1’ in the Status register associated with an Interrupt source shows that the interrupt source is
pending. The Status register is read-only. To clear a bit in the Status register, the associated bit in the
Clear register must be written with a ‘1.’
•
A ’1’ the bit position of the Mask register associated with an Interrupt source ensures that the hardware
interrupt will never be passed on to the DSS interrupt controller. A ‘0’ in the bit position of the Mask
register associated with an Interrupt source will cause the DSS interrupt controller to see a VIP Parser
interrupt in the event the hardware in the parser triggers it.
•
A ‘1’ in the bit position of the Clear register associated with an Interrupt source clears the hardware
interrupt status register until the next time the hardware triggers it. After a Clear, the CPU should set
the bit back to a ‘0.’ Otherwise, the hardware would not be able to set any subsequent interrupts of the
same type.
