A status interrupt is generated by bits BOFF, EWARN, RXOK, TXOK, or LEC. BOFF and
EWARN generate an error interrupt, and RXOK, TXOK, and LEC generate a status
change interrupt if EIE and SIE respectively are set to enabled in the CANCTRL register.
A change of bit EPASS and a write to RXOK, TXOK, or LEC will never create a status
interrupt.
Reading the CANSTAT register will clear the Status Interrupt value in the CANIR register.
Description
Error passive
The CAN controller is in the error active state.
The CAN controller is in the error passive state as defined in the CAN
2.0 specification .
Warning status
Both error counters are below the error warning limit of 96.
At least one of the error counters in the EML has reached the error
warning limit of 96.
Busoff status
The CAN module is not in busoff state.
The CAN controller is in busoff state.
