CAN General Interrupt Register - CANGIT
This flag does not generate an interrupt.
• Bit 1 – BOFF: Bus Off Mode
BOFF gives the information of the state of the CAN channel. Only entering in bus off mode gen-
erates the BOFFIT interrupt.
• Bit 0 – ERRP: Error Passive Mode
ERRP gives the information of the state of the CAN channel. This flag does not generate an
interrupt.
• Bit 7 – CANIT: General Interrupt Flag
This is a read only bit.
• Bit 6 – BOFFIT: Bus Off Interrupt Flag
Writing a logical one resets this interrupt flag. BOFFIT flag is only set when the CAN enters in
bus off mode (coming from error passive mode).
• Bit 5 – OVRTIM: Overrun CAN Timer
Writing a logical one resets this interrupt flag. Entering in CAN timer overrun interrupt handler
also reset this interrupt flag
• Bit 4 – BXOK: Frame Buffer Receive Interrupt
Writing a logical one resets this interrupt flag. BXOK flag can be cleared only if all CONMOB
fields of the MOb’s of the buffer have been re-written before.
