Field
Description
DBL_EF
Double Transmit Message Buffer Lock Error Flag — This flag is set if the application tries to
lock the transmit side of a double transmit message buffer. In this case, the CC does not grant
the lock to the transmit side of a double transmit message buffer.
0 No such event
1 Double transmit buffer lock error occurred
SBCF_EF
System Bus Communication Failure Error Flag — This flag is set if a system bus access was
not finished within the required amount of time (see Section 26.6.19.2, System Bus Access
Timeout).
0 No such event
1 System bus access not finished in time
FID_EF
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
DPL_EF
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 Protocol Configuration Register 24 (FR_PCR24).
0 No such error occurred
1 Dynamic payload length error occurred
SPL_EF
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 Protocol
Configuration Register 19 (FR_PCR19).
0 No such error occurred
1 Static payload length error occurred
NML_EF
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 Network Management
Vector Length Register (FR_NMVLR). 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
NMF_EF
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 Network Management
Vector Registers (FR_NMVR0–FR_NMVR5)) are not updated.
0 No such error occurred
1 Network management frame error occurred
ILSA_EF
Illegal System Bus Address Error Flag — This flag is set if the external system bus subsystem
has detected an access to an illegal system bus address from the CC (see Section 26.6.19.1,
System Bus Illegal Address Access).
0 No such event
1 Illegal system bus address accessed
