Description
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.

Description
Error Mode Changed Interrupt Flag — This flag is set when the value of the ERRMODE bit field in the Protocol
Status Register 0 (PSR0) is changed by the controller.
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 Protocol Operation Control Register (POCR),
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 Section 22.7.4, Protocol Control Command Execution.
0 No such event.
1 Illegal protocol control command detected.
Protocol Engine Communication Failure Interrupt Flag — This flag is set if the controller has detected a
communication failure between the protocol engine and the controller host interface
0 No such event.
1 Protocol Engine Communication Failure detected.
Protocol State Changed Interrupt Flag — This flag is set when the protocol state in the PROTSTATE field in
the Protocol Status Register 0 (PSR0) has changed.
0 No such event.
1 Protocol state changed.
