Set the IPIPEIF_CFG1[15:14] INPSRC1 bit field to 2 and the IPIPEIF_CFG1[3:2] INPSRC2 bit field to 0.
In this configuration, dark frame subtraction is performed and data is sent to the ISIF module. The ISIF processes the data and sends it back to the IPIPEIF module before the data is pushed to the IPIPE or RSZ modules. There are two possible dark frame subtractions: the first is with data coming from the VP and the dark frame coming from BL; the second is with data coming from BL and the dark frame coming from the VP.
Figure 9-47 shows the data path.
