For each video line, the length (in bytes) will be determined. The LINE_LEN_1 and LINE_LEN_0 registers 0x75 and 0x76 can be used to read the line count for the most recent video frame. If the line length is not stable throughout the frame, the length of the last line of the frame will be reported. Line Count may not be consistent when receiving multiple CSI-2 video streams differentiated by VC-ID. An interrupt may be enabled based on a change in the LINE_LEN value. If interrupts are enabled, the LINE_LEN registers will be latched at the interrupt and held until read by the processor through I2C.
