Just don't block interrupts waiting (forever) for transfer complete or for free Tx buffer. Is there free Tx buffer? Then fill it and clear buffer flag. All buffers busy? Then postpone Tx and exit.</P><P></P><P>Edward</P></BODY></HTML> Fri, 08 May 2015 03:45:33 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Transmission-in-Receive-interrupt/m-p/410742#M11122 kef2 2015-05-08T03:45:33Z
