Each VIP port can be set up to trigger an interrupt if the picture size varies from a pre-programmed expected picture size. This interrupt is supported only for the Active Video portion of the input video and not for the Vertical Ancillary portion. Also this interrupt is only support for source number 0 in multi channel capture.
The interrupts are named PrtASrc0Size and PrtBSrc0Size. They are described in Table 9-19, VIP_PARSER Interrupt Events
For Port A, the expected active video picture size values are programmed in VIP_XTRA_PORT_A[11:0] SRC0_NUMLINES and VIP_XTRA_PORT_A[27:16] SRC0_NUMPIX. For PortB, the expected active video picture size values are programmed in VIP_XTRA_PORT_B[11:0] SRC0_NUMLINES and VIP_XTRA_PORT_B[27:16] SRC0_NUMPIX.
Picture Size Interrupt reflects the Active Video going into the DRAM. If cropping is enabled for Srcnum=0, the Picture Size is the post-cropped size.
