CAN0 Error Interrupt Status Register (CAN0ERIST)
<Address:H'0080 1014>
W = : Only writing a 0 is effective; when you write a 1, the previous value is retained.
When using CAN interrupts and the interrupt sources are associated with errors, this register lets
you know which source generated the interrupt.
(1) EIS (CAN Bus Error Interrupt Status) bit (D5)
This bit is set to 1 when a communication error is detected. This bit is cleared by writing a 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 is cleared by
writing a 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 is cleared by writing a 0
in software.
When writing to the CAN error interrupt status, make sure the bits you want to clear are set to 0
and all other bits are set to 1. The bits thus set to 1 are unaffected by writing in software and retain
the value they had before you write.
