The register holds one set of the protocol related individual interrupt flags. The application clears an
interrupt flag by writing a ‘1’ to it. Writing ‘0’ will not change the state of the flag. If the application clears
a flag while the FlexRay module sets this flag at the same time, then that flag remains set.

Transmission across boundary on channel A Interrupt Flag — This flag is set when the frame transmission
on channel A crosses the slot boundary. This is related to the transmission across slot boundary violation as
described in the FSP process of the FlexRay protocol.
0 No such event.
1 Transmission across boundary violation occurred on channel A.
Timer 2 Expired Interrupt Flag — This flag is set whenever timer 2 expires.
0 No such event.
1 Timer 2 has reached its time limit.
Timer 1 Expired Interrupt Flag — This flag is set whenever timer 1 expires.
0 No such event
1 Timer 1 has reached its time limit
Cycle Start Interrupt Flag — This flag is set when a communication cycle starts.
0 No such event
1 Communication cycle started.
Error Mode Changed Interrupt Flag — This flag is set when the value of the ERRMODE bit field in the
Protocol Status Register 0 (PSR0)
0 No such event.
1 ERRMODE field changed.
Illegal Protocol Control Command Interrupt Flag — This flag is set when the PE tries to execute a protocol
control command, which was issued via the POCCMD field of the
and detects that this protocol control command is not allowed in the current protocol state. In this case the
command is not executed. For more details, see
0 No such event.
1 Illegal protocol control command detected.
Protocol Engine Communication Failure Interrupt Flag — This flag is set if the FlexRay module has detected
a communication failure between the protocol engine and the controller host interface
0 No such event.
1 Protocol Engine Communication Failure detected.
