Introduction
The Xilinx® LogiCORE™ IP Controller Area Network
(CAN) product specification defines the architecture
and features of the Xilinx CAN controller core. This
document also defines the addressing and functionality
of the various registers in the design, in addition to
describing the user interface. The scope of this
document does not extend to describing the CAN
protocol and assumes knowledge of the specifications
described in the Reference Documents section.
