Hello everybody

 

I have a question about CSI camera parallel interface.
The document IMXDQRM in Section 1.4, 9.2.1.1, 37.3.1.1 is written that a parallel camera interface is up to 20 bits.

But in Section 37.4.3.2.1 is written:

37.4.3.2.1 Parallel Interface
In parallel interface a single value in each clock arrives, except when working in BT.1120
mode, In Which two values arrive in each cycle. Each value can be 8-16 bit wide
According to configuration of DATA_WIDTH. If DATA_WIDTH is configured to N,
then 20-N LSB bits are ignored.

Is it possible to work with this interface so that you can receive a 20-bit words? If so, how to configure the interface?


Michal
