It is mentioned in the table 87 (DCMI characteristics, stm32f405/407 datasheet, Rev7) that max DCMI_PIXCLK is 54 MHz, and it's mentioned in the RM0090 that this peripheral is capable of up to 54MBytes/s transfer rate. The question is, how number of data lines affects this throughput rate? is this rate just for 8 data lines (because of that it uses whole of data register)?
