If the Reset bit in the C0CTLR register is changed from 0 (operation mode) to 1 (reset/initialization mode) in
order to place the CAN module from CAN operation mode into CAN reset/initialization mode, always be sure
to check that the State_Reset bit in the C0STR register is set to 1 (reset mode).
Similarly, if the Reset bit is changed from 1 to 0 in order to place the CAN module from CAN reset/
initialization mode into CAN operation mode, always be sure to check that the State_Reset bit is set to 0
(operation mode).
The procedure is described below.
