Note 1: PH2 = max (PH1, IPT), that is specified in CAN protocol, cannot be met.
Note 2: As for Can module clock, select CPUCLK/4 in CAN Clock Select Register.
Note: It does not mean that the communication at the above baud rate settings is guaranteed. Sufficient evaluation and
verification are required before use.
