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 a ‘0’ will not change the state of the flag. If the application tries
to clear a flag and the FlexRay module sets this flag at the same ¹³×time, then that flag remains set.

Receive Buffer Interrupt Enable — This flag controls if the receive buffer interrupt line is asserted when the
RBIF flag is set.
0 Disable interrupt line
1 Enable interrupt line
Transmit Interrupt Enable — This flag controls if the transmit buffer interrupt line is asserted when the TBIF
flag is set.
0 Disable interrupt line
1 Enable interrupt line
Fatal Protocol Error Interrupt Flag — This flag is set when the protocol engine has detected a fatal protocol
error. In this case, the protocol engine goes into the

2) transmission across slot boundary violation, as described in the FSP process of the FlexRay protocol
0 No such event.
1 Fatal protocol error detected.
Internal Protocol Error Interrupt Flag — This flag is set when the protocol engine has detected an internal
protocol error. In this case, the protocol engine goes into the
error occurs when the protocol engine has not finished a calculation and a new calculation is requested. This
can be caused by a hardware error.
0 No such event.
1 Internal protocol error detected.
Illegal Protocol Configuration Interrupt Flag — This flag is set when the protocol engine has detected an
illegal protocol configuration parameter setting. In this case, the protocol engine goes into the

The protocol engine checks the listen_timeout value programmed into the
