22.5.2.16 Message Buffer Interrupt Vector Register (MBIVEC)
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 22.6.19.2, 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 (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 (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 (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 (NMVR0–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 controller (see
Section 22.6.19.1, System Bus Illegal
0 No such event
1 Illegal system bus address accessed
