MultiCAN, V2.0
22.7.7 MSC Handling
The MSC bit field is updated only for those message objects that are indicated by the
valid RCE or TCE entry while the corresponding bit MSGVAL is set. The message
number taken into account for an update is defined in the respective bit fields
RCEMSGNR or TCEMSGNR.
Checking for the receive/transmit condition takes place when the end of the transmit
enable window of the following time marks is reached. Because the transmit enable
window length is known after each time mark (even if no message shall be sent out), this
point in time can be used for the receive and the transmit check.
This feature makes it possible to have a positive check result even if the message in the
preceding time window finishes during the transmit enable window.
A transmission attempt is defined as failed if a message object valid for transmission
could not be transferred on the CAN bus. A transmit trigger being active without a valid
message object being found is not considered as a transmission attempt.
