There isn't much (any?) documentation. But you only need to understand the operation of the core, and its interfaces, not how it works internally. The core basically replicates a Philips SJA1000 CAN controller - all the registers are the same. So just look at

There are 2 interfaces (at least in the Verilog version) - Wishbone and 8051. The Wishbone interface is specified by Opencores - get the spec from

You can get the (Intel) 8051 spec from the datasheets and app notes from any of the vendors making 8051 clone chips - start here
