eCAN: Unexpected Cessation of Transmit Operation

Revision(s) Affected

0, A, B, C, D, E, F and G

Details

In rare instances, the cessation of message transmission from the eCAN module has been observed (while the receive operation continues normally). This anomalous state may occur without any error frames on the bus.

Workaround(s)

The Time-out feature (MOTO) of the eCAN module may be employed to detect this condition. When this occurs, set and clear the CCR bit (using the CCE bit for verification) to remove the anomalous condition.
