The CAN reset/initialization mode is activated upon MCU reset or by setting the Reset bit in the C0CTLR
register to 1. If the Reset bit is set to 1, check that the State_Reset bit in the C0STR register is set to 1.
Entering the CAN reset/initialization mode initiates the following functions by the module:
