In your case this would be all buffers.<BR /><BR />The CANxTAAK register reports if the abort was successful. A 1 signifys that the corresponding message buffer is now empty. A zero signifys that the abort was unsuccessful and the message was transmitted.<BR /><BR />Hope that helps.</BODY></HTML> Thu, 04 Jan 2007 19:52:02 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/MSCAN-in-MC9S12DG128/m-p/141900#M3332 DannyM83 2007-01-04T19:52:02Z
