Abstract
A CAN module comprises a buffer memory comprising a data and address input and a plurality of addressable buffers, a data receive register being coupled with the buffer memory receiving data from a serial data stream, a filter register, a comparator comparing the filter register value with an identifier transmitted in the serial data stream generating an acceptance signal, a buffer pointer coupled with the comparator to receive the acceptance signal, and an address register receiving an address from the buffer pointer for addressing the buffer memory. The arrangement can dynamically assign any filter register to any buffer within the buffer memory.
