Description
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 POC:halt state immediately. The fatal protocol errors are:
1) pLatestTx violation, as described in the MAC process of the FlexRay protocol
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 POC:halt state immediately. An internal protocol
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 POC:halt state
immediately.
The protocol engine checks the listen_timeout value programmed into the Protocol Configuration Register 14
(PCR14) and Protocol Configuration Register 15 (PCR15) when the CONFIG_COMPLETE command was sent
by the application via the Protocol Operation Control Register (POCR). If the value of listen_timeout is equal to
zero, the protocol configuration setting is considered as illegal.
0 No such event.
1 Illegal protocol configuration detected.
