The DM6431 device has a High-End Controller Area Network Controllers (HECC). The HECC uses

established protocol to communicate serially with other controllers in harsh environments. The HECC is

fully compliant with the Controller Area Network (CAN) protocol, version 2.0B.

Key features of the HECC include the following:

• CAN, version 2.0B compliant

• 32 RX/TX message objects

• 32 receive identifier masks

• Programmable wake-up on bus activity

• Programmable interrupt scheme

• Automatic reply to a remote request

• Automatic re-transmission in case of error or loss of arbitration

• Protection against reception of a new message

• 32-bit time stamp

• Local network time counter

• Programmable priority register for each message

• Programmable transmission and reception time-out

• HECC/SCC mode of operation

• Standard-Extended Identifier

• Self-test mode

For more details on the HECC, see the TMS320DM643x High-End CAN Controller (HECC) User's Guide

(literature number SPRU981).

Software must not access "Reserved" locations of the HECC. Access to HECC "Reserved" locations may

hang the device.
