10.11.9 CAN Clock Control Register

Note:

The user must ensure the input clock source is 640 MHz or less. Operation with input reference frequency above 640 MHz will result in unpredictable behavior.
The CANCLKDIVx divider value must not be changed during CAN module operation.
The user must ensure the maximum clock output frequency of the divider is 80 MHz or less.
