ISS ISP sensor capture

Hello,

I Have a question regarding the sensor capture process and interrupts.

We are using APPRO DM8127 IPNC and we looked into issdrv_captureApi.c.

We can see that the buffer switch to the resizer and new frame queue to the flow is done under isif VDINT0 irq (which is set to isif_reg->VDINT0 = isif_reg->VDINT1 = isif_reg->VDINT2 = pObj->createArgs.scParams[0].inHeight - 5).

Can someone please explain us what is the logic behind that? (why not consume the frame after the resizer finished with it).

Mabye A timeline of the process can help.

Thanks,

Tal
