17.3.1 Scenario 1: Normal case, no message lost
17.3 Set and clear mechanism of the FullCAN interrupt
The interrupt pending bit (IntPndx) gets asserted in case of an accepted FullCAN
message and if the interrupt of the according FullCAN Object is enabled (enable bit
FCANIntxEn) is set).
During the last write access from the data storage of a FullCAN message object the
interrupt pending bit of a FullCAN object (IntPndx) gets asserted.
Each of the FullCAN Interrupt Pending requests gets cleared when the semaphore bits of
a message object are cleared by Software (ARM CPU).
The Message Lost bit of a FullCAN message object gets asserted in case of an accepted
FullCAN message and when the FullCAN Interrupt of the same object is asserted already.
During the first write access from the data storage of a FullCAN message object the
Message Lost bit of a FullCAN object (MsgLostx) gets asserted if the interrupt pending bit
is set already.

The Message Lost bit of a FullCAN message object gets cleared when the FullCAN
Interrupt of the same object is not asserted.
During the first write access from the data storage of a FullCAN message object the
Message Lost bit of a FullCAN object (MsgLostx) gets cleared if the interrupt pending bit
is not set.
Special precaution is needed for the built-in set and clear mechanism of the FullCAN
Interrupts. The following text illustrates how the already existing Semaphore Bits (see

features (IntPndx, MsgLstx) will behave.
