CAN Controller Module
This chapter describes the controller area network (CAN) module available on
some members of the ’24x/’240x family. The interface signals, configuration
registers, and mailbox RAM are described in detail; however, the CAN protocol
itself is not discussed in depth. For details on the protocol, refer to
CAN Specifi-
cations, Version 2.0 , by Robert Bosch GmBH, Germany. The CAN module is
a full-CAN controller designed as a 16-bit peripheral and is fully compliant with
the CAN protocol, version 2.0B.
