• P_OVR: Preview Datapath Overflow
0: No overflow
1: An overrun condition has occurred in input FIFO on the preview path. The overrun happens when the FIFO is full and an
attempt is made to write a new sample to the FIFO. This flag is reset after a read operation.
• C_OVR: Codec Datapath Overflow
0: No overflow
1: An overrun condition has occurred in input FIFO on the codec path. The overrun happens when the FIFO is full and an
attempt is made to write a new sample to the FIFO. This flag is reset after a read operation.
• CRC_ERR: CRC Synchronization Error
0: No CRC error in the embedded synchronization frame (SAV/EAV)
1: The CRC_SYNC is enabled in the control register and an error has been detected and not corrected. The frame is dis-
carded and the ISI waits for a new one. This flag is reset after a read operation.
• FR_OVR: Frame Rate Overrun
0: No frame overrun.
1: Frame overrun, the current frame is being skipped because a vsync signal has been detected while flushing FIFOs. This
flag is reset after a read operation.
