The CAN controller clock is derived from the CIP-51 system clock. The CAN control-
ler clock must be less than or equal to 25 MHz.
00: CAN controller clock = System Clock/1.
01: CAN controller clock = System Clock/2.
10: CAN controller clock = System Clock/4.
11: CAN controller clock = System Clock/8.
