6.2.4.5.2.4 Camera ISP CSI2 Synchronization Codes
Data reception from the image-sensor module uses four synchronization codes embedded in the serial
bit-stream:
•
FSC: Identifies the start of a new frame
•
LSC: Identifies the start of a new line; received for every line
•
LEC: Identifies the end of a line; received for every line
•
FEC: Identifies the end of the current frame
summarizes the synchronization code values.
