53.5.8 Hardware Reset Description
After hardware reset, the registers of the MCAN hold the reset values listed in the register descriptions. Additionally the Bus_Off state is reset and the output CANTX is set to recessive (HIGH). The value 0x0001 (MCAN_CCCR.INIT = ‘1’) in the CC Control register enables software initialization. The MCAN does not influence the CAN bus until the processor resets MCAN_CCCR.INIT to ‘0’.
