For some purpose i need to run DCMI interface with maximum frequency(it is 54MHz, right?), i provided pixclk pin with 56MHz clock(sysclock divided by 3 coming out of mco2 pin) but it seems that overrun occurs on DCMI fifo.
What is the maximum applicable frequency of this interface and how can it be generated?
