Camera interface
The camera interface receives data from a sensor in parallel mode (8 to 14-bits) by storing a
full line in a buffer memory, then requesting a DMA transfer or interrupting the processor.
When all the lines of a frame are transferred, a frame sync interrupt is generated.
Main features:
●
●
●
●
●
Supports both hardware synchronization (HSYNC and VSYNC signals) and embedded
synchronization (ITU656 or CSI2).
Data carried by the bus can be:
–
–
–
–
Data is stored in a 2048 x 32 buffer memory
The camera interface can be assigned to two different set of pins. When using data
greater than 8-bits, it is not possible to use the MII interface.
Max pixel clock frequency is 100 MHz
