(1) BEIEN (CAN Bus Error Interrupt Request Enable) bit (Bit 5)
The BEIEN bit enables or disables the interrupt requests to be generated when CAN bus errors occurred.
CAN bus error interrupt requests are enabled by setting this bit to "1".
(2) EPIEN (Error Passive Interrupt Request Enable) bit (Bit 6)
