• 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
