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.
