The MBI, consisting of mailboxes and a local acceptance filter mask (LAFM), stores CAN
transmit/receive messages (identifiers, data, etc.) Transmit messages are written by the CPU.
For receive messages, the data received by the CDLC is stored automatically.
The MPI, consisting of a bus interface, control register, status register, etc., controls HCAN
internal data, status, and so forth.
The CDLC transmits and receives of messages conforming to the Bosch CAN Ver. 2.0B active
standard (data frames, remote frames, error frames, overload frames, inter-frame spacing), as
well as CRC checking, bus arbitration, and other functions.
