When using the CAN interrupt, the CiEISTR register determines an error interrupt source.
Bits BOIS, EPIS, and BEIS are not automatically set to 0 (interrupt not requested) even if the interrupt is
acknowledged. Set these bits to 0 by a program.
Use the MOV instruction to set each bit in the CiEISTR register to 0. Write a 0 to the bit which is to set to 0, and
write a 1 to the bit which is to remain unchanged.
Refer to 23.4 CAN Interrupts for details.
The BOIS bit becomes 1 when the CAN module is placed in a bus-off state.
NOTE:
The EPIS bit becomes 1 when the CAN module is placed in an error passive state.
NOTE:
The BEIS bit becomes 1 when a CAN bus error is detected.

NOTES:
