This description is based on the B256 description from CRI Channel blog (in Japanese).

P256 is a paletted video codec that employs prediction and B256 entropy coding.

B256 (internal CRI name for the technology) seems to be Tunstall coding (like in Duck TrueMotion 1) where one byte corresponds to a codebook entry with a variable amount of symbols.
