Hello, I want to use the MSCAN Module of the DSP56807 for a hart real-time application with periodic transmission of messages in a fix time slot. The automatic retransmission of messages produce an undesired delay in time. Therefore I want to know if it is possible to suppress this procedure in the MSCAN. Referring to the specification for Time-Triggered CAN (TTCAN) of Robert Bosch, automatic retransmission is not allowed and is to be disabled for exclusive time windows. But how can I deactivate the retransmission of CAN messages for timeliness garantees ? Are there maybe other possibilities in order to achieve the same ? In addition it would be helpful to know the maximum time duration from request for an abort of a message in progress until the abortion is done and acknowledged. A lot of thanks to all which can help me in this matter. Tatjana
