System Bus Communication Failure Error Flag — This flag is set if the FlexRay module was not able to
transmit or receive data via the system bus in time. In the case of writing, data is lost; in the case of reading, the
transmission onto the FlexRay bus is stopped for the current slot and resumed in the next slot.
0 No such event
1 System bus communication failure occurred
Frame ID Error Flag — This flag is set if the frame ID stored in the message buffer header area differs from the
frame ID stored in the message buffer control register.
0 No such error occurred
1 Frame ID error occurred
Dynamic Payload Length Error Flag — This flag is set if the payload length written into the message buffer
header field of a single or double transmit message buffer assigned to the dynamic segment is greater than the
maximum payload length for the dynamic segment as it is configured in the corresponding protocol configuration
register field max_payload_length_dynamic in the
0 No such error occurred
1 Dynamic payload length error occurred
Static Payload Length Error Flag — This flag is set if the payload length written into the message buffer header
field of a single or double transmit message buffer assigned to the static segment is different from the payload
length for the static segment as it is configured in the corresponding protocol configuration register field
payload_length_static in the
0 No such error occurred
1 Static payload length error occurred
Network Management Length Error Flag — This flag is set if the payload length written into the header
structure of a receive message buffer assigned to the static segment is less than the configured length of the
Network Management Vector as configured in the
In this case the received part of the Network Management Vector will be used to update the Network
Management Vector.
0 No such error occurred
1 Network management length error occurred
Network Management Frame Error Flag — This flag is set if a received message in the static segment with a
Preamble Indicator flag PP asserted has its Null Frame indicator flag NF asserted as well. In this case, the Global
Network Management Registers (see
updated.
0 No such error occurred
1 Network management frame error occurred
Illegal System Memory Access Error Flag — This flag is set if the external system memory subsystem has
detected and indicated an illegal system memory access from the FlexRay module. The exact meaning of an
illegal system memory access is defined by the current implementation of the memory subsystem.
0 No such event.
1 Illegal system memory access occurred.
