  1. Mixed registers are registers that have read only, write only, and read write bits grouped together.
Note: The VCU encoder and decoder output streams are stored in DDR memory (either PS or PL) and cannot be routed directly from encoder to decoder and vice versa, so it is required to use DDR (PS or PL) with the VCU encoder and decoder.
