W= : Only writing 0 is effective. Writing 1 has no effect, the bit retains the value it had before writing.
When using CAN interrupts, checking this register will help to find the cause of interrupt if the
interrupt has been generated due to an error.
(1) EIS (CAN bus error interrupt status) bit (D5)
This bit is set to 1 when a communication error is detected. This bit can be cleared by writing 0 in
software.
(2) PIS (Error passive interrupt status) bit (D6)
This bit is set to 1 when the CAN module goes to an error-passive state. This bit can be cleared
by writing 0 in software.
(3) OIS (Bus off interrupt status) bit (D7)
This bit is set to 1 when the CAN module goes to a bus-off state. This bit can be cleared by writing
0 in software.
When writing to the CAN Error Interrupt Status Register, be sure to write 0 for the bits to be cleared
and 1 for all other bits. Writing 1 in software does not affect any bit of this register, the bit retains the
value it had before writing.
