• Universal counter exceeded event interrupt (CAN_GIM.UCEIM, CAN_GIS.UCEIS, CAN_GIF.UCEIF):
There is an overflow of the universal counter (in time stamp mode or event counter mode) or the counter has
reached the value 0x0000 (in watchdog mode).
• Receive message lost event interrupt (CAN_GIM.RMLIM, CAN_GIS.RMLIS, CAN_GIF.RMLIF): A mes-
sage is received for a mailbox that currently contains unread data. At least 1 bit in the CAN_RMLn register is
set. If the bit in CAN_GIS

CAN_AA1.MB bits maintain state even after the corresponding mailbox n is disabled
• Access to unimplemented address event interrupt (CAN_GIM.UIAIM, CAN_GIS.UIAIS,
CAN_GIF.UIAIF): There was a CPU access to an address which is not implemented in the controller mod-
ule.
• Wake-up event interrupt (CAN_GIM.WUIM, CAN_GIS.WUIS, CAN_GIF.WUIF): The CAN module has
left the sleep mode because of detected activity on the CAN bus line.
• Bus-off event interrupt (CAN_GIM.BOIM, CAN_GIS.BOIS, CAN_GIF.BOIF): The CAN module has en-
tered the bus-off state. This interrupt source is active if the status of the CAN core changes from normal opera-
tion mode to the bus-off mode. If the bit in the
mode is still active, then this bit is not set again. If the module leaves the bus-off mode, the bit in the

• Error-passive event interrupt (CAN_GIM.EPIM, CAN_GIS.EPIS, CAN_GIF.EPIF): The CAN module
has entered the error-passive state. This interrupt source is active if the status of the CAN module changes from
the error-active mode to the error-passive mode. If the bit in the

• Error warning transmit interrupt (CAN_GIM.EWTIM, CAN_GIS.EWTIS, CAN_GIF.EWTIF): The CAN
transmit error counter (CAN_CEC.TXECNT) has reached the warning limit. If the bit in the
registers is cleared and the error warning mode is still active, this bit is not set again. If the module
