CAN Controller Software Initialization
The very first step of the initialization is the CAN controller input clock selection. A divide-by-2
prescaler is enabled by default after reset
prescaler. The purpose of the prescaler selection is:

– to ensure that the CAN controller is operable when f osc is over 10 MHz (bit CMOD =0)
– to achieve the maximum CAN baudrate of 1 Mbaud when f osc is 8 MHz (bit CMOD=1)
