CAN General Interrupt Register - CANGIT
• Bit 2 – ENFG: Enable Flag
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
generates 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
Initial Value
Read/Write
– 1 - receiver busy: set by hardware as long as a frame is received or monitored.
– 0 - CAN controller disable: because an enable/standby command is not
– 1 - CAN controller enable.
– 0 - no bus off mode.
– 1 - bus off mode.
– 0 - no error passive mode.
– 1 - error passive mode.
Bit
– 0 - no interrupt.
– 1 - CAN interrupt: image of all the CAN controller interrupts except for OVRTIM
– 0 - no interrupt.
– 1 - bus off interrupt when the CAN enters in bus off mode.
– 0 - no interrupt.
– 1 - CAN timer overrun interrupt: set when the CAN timer switches from 0xFFFF to 0.
