Look into <STRONG>Table&nbsp;88. Connection of interrupt sources to the NVIC User Manual UM10912</STRONG></P> <P>Best Regards, Miguel.</P> Mon, 03 Jul 2023 18:13:11 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC546-MCAN-Channel1-not-working/m-p/1680671#M53310 Miguel04 2023-07-03T18:13:11Z
