CANGIE – CAN General Interrupt Enable Register
• Bit 3 – SERG: Stuff Error General
Writing a logical one resets this interrupt flag.
• Bit 2 – CERG: CRC Error General
Writing a logical one resets this interrupt flag.
• Bit 1 – FERG: Form Error General
Writing a logical one resets this interrupt flag.
• Bit 0 – AERG: Acknowledgment Error General
Writing a logical one resets this interrupt flag.
• Bit 7 – ENIT: Enable all Interrupts (except for CAN Timer Overrun Interrupt)
• Bit 6 – ENBOFF: Enable Bus Off Interrupt
• Bit 5 – ENRX: Enable Receive Interrupt
Read/Write
Initial Value
– 0 - no interrupt
– 1 - burst receive interrupt: set when the frame buffer receive is completed
– 0 - no interrupt
– 1 - stuff error interrupt: detection of more than 5 consecutive bits with the same
– 0 - no interrupt
– 1 - CRC error interrupt: the CRC check on destuffed message does not fit with the
– 0 - no interrupt
– 1 - form error interrupt: one or more violations of the fixed form in the CRC delimiter,
– 0 - no interrupt
– 1 - acknowledgment error interrupt: no detection of the dominant bit in acknowledge
– 0 - interrupt disabled
