When using the CAN interrupt, the CiEISTR register indicates the source of the generated error inter-
rupt. The BOIS, EPIS and BEIS bits are not automatically set to "0" (no interrupt requested) even if an
interrupt is acknowledged. Set these bits to "0" by program.
Use the MOV instruction, instead of the bit clear instruction, to set each bit in the CiEISTR register to "0".
Refer to 23.4 CAN Interrupt for details.

The BOIS bit is set to "1" when the CAN module is placed in a bus-off state.
The EPIS bit is set to "1" when the CAN module is placed in an error passive state.
The BEIS bit is set to "1" when a CAN bus error is detected.
