Use the C1BRP register to select the CAN protocol layer base system clock (f
determined by the value set to the C1SYNC register.
While in normal operation mode (C1DEF register's MOM bit = 0), the C1BRP register can only be accessed
when the initialization mode has been set (C1CTRL register's INIT bit = 1).
This register can be read/written in 16-bit units.
Caution While in diagnostic processing mode (C1DEF register's MOM bit = 1), the C1BRP register
can only be accessed when the initialization mode has been set (C1CTRL register's INIT bit
