39.4.3
Register Name: ISI_SR
Access Type: Read
Reset Value: 0x0
• SOF: Start of Frame
0: No start of frame has been detected.
1: A start of frame has been detected.
• DIS: Image Sensor Interface Disable
0: The image sensor interface is enabled.
1: The image sensor interface is disabled and stops capturing data. The DMA controller and the core can still read the
FIFOs.
• SOFTRST: Software Reset
0: Software reset not asserted or not completed.
1: Software reset has completed successfully.
• CDC_PND: Codec Request Pending
0: No request asserted.
1: A codec request is pending. If a codec request is asserted during a frame, the CDC_PND bit rises until the start of a new
frame. The capture is completed when the flag FO_C_EMP = 1.
• 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.
• FO_C_OVF: FIFO Codec 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.
