The information in RSTAT[1:0] is redundant as mentioned under Table 13-10 in RM. You can use the automatic recovery mode or use the BORM = 1 for recovery upon user request.</P> <P>I hope it helps you to solve your issue.</P> <P>Have a nice day.</P> <P>Stano.</P> <P>&nbsp;</P> Wed, 09 Jun 2021 11:22:39 GMT StanoA 2021-06-09T11:22:39Z https://community.nxp.com/t5/S12-MagniV-Microcontrollers/CAN-Bus-off-register-in-MSCAN/m-p/1289777#M17892 <P>In&nbsp;MSCAN Receiver Flag Register (CANRFLG), to monitor the Bus-off state which bits should we use in our software? In CANRFLG register, bits - RSTAT[1:0] or TSTAT[1:0] should we use to get the Bus-off status ?&nbsp;</P> Wed, 09 Jun 2021 08:45:55 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/CAN-Bus-off-register-in-MSCAN/m-p/1289777#M17892 pratibhasurabhi 2021-06-09T08:45:55Z https://community.nxp.com/t5/S12-MagniV-Microcontrollers/CAN-Bus-off-register-in-MSCAN/m-p/1289878#M17893 <P>Hello Pratibhasurabhi,</P> <P>This MCU has implemented the MSCAN_V3 so you need to monitor TSTAT[1:0] bits the decode the Bus-off state.
