Each interrupt flag of the global interrupt flag register [CANxGIF] will be set to "1" if the corresponding global
interrupt condition has met. When the global interrupt flag is set to "1", if the corresponding bit in the global
interrupt mask register [CANxGIM] is "1" (interrupt enabled), the CAN global interrupt (INTCANxGLB) will be
"High".
The [CANxGIF] register (Lower 8bits) can be cleared by writing "1" to the corresponding bit in the [CANxGIF]
register. A write of "0" is invalid.
R Read as "0".
Remote frame pending flag
0: No remote frame has been received.
R/W 1: Remote frames have been received. (in the receive mailbox)
This bit will not be set when matching with the transmission mailbox for which the <RFH> bit is
"1".
Wake-up interrupt flag
R/W 0: In sleep mode or normal operation mode
1: Sleep mode has been canceled.
Receive message lost interrupt flag
0: No receive message lost error has occurred.
R/W
1: A receive message lost error has occurred in at least one mailbox configured as a receive
mailbox.
Transmission abort flag
R/W 0: No transport abort has occurred.
1: Transport abort has occurred. (At least one bit in the [CANxAA] register is set.)
Time stamp counter overflow interrupt flag
R/W 0: No overflow has occurred in the time stamp counter after this bit was last cleared.
1: There was at least one overflow of the time stamp counter after this bit was last cleared.
Bus off interrupt flag
R/W 0: The CAN controller is in bus on mode.
1: The CAN controller is in bus off mode.
Error passive interrupt flag
R/W 0: The CAN controller is in error active mode.
1: The CAN controller is in error passive mode.
Warning level interrupt flag
R/W 0: None of the error counters have reached the warning level.
1: At least one of the error counters has reached the warning level.
