About the TXE bit of S12G128 msCAN

Hello,

I now make the demo code to send CAN message using S12G128.

 

The following action is observed;
in normal situation(non-loopback configuration),
TXE bit of corresponded Tx buffer is not set after CAN message sending
and the same message has continued to be sent.
We use one TWR-S12G128 board as a message sender, and no listener.

 

Does this action meet the spec of S12G128?

 

On the other hand, in loopback configuration, we can observe the setting of TXE bit,
so I think it may be required the listener on the demo environment.
