Field
Description

FRLB_EF
Frame Lost Channel B Error Flag
— This flag is set if a complete frame was received on channel B but could
not be stored in the selected individual message buffer because this message buffer is currently locked by the
application. In this case, the frame and the related slot status information are lost.
0 No such event
1 Frame lost on channel B detected
Frame Lost Channel A Error Flag
— This flag is set if a complete frame was received on channel A but could
not be stored in the selected individual message buffer because this message buffer is currently locked by the
application. In this case, the frame and the related slot status information are lost.
0 No such error
1 Frame lost on channel A detected
Protocol Command Ignored Error Flag
— This flag is set if the application has issued a POC command by
writing to the POCCMD field in the
Protocol Operation Control Register (POCR)
while the BSY flag is equal to
‘1’. In this case the command is ignored by the FlexRay module and is lost.
0 No such error
1 POC command ignored
Receive FIFO Overrun Channel B Error Flag
— This flag is set when an overrun of the Receive FIFO for
channel B occurred. This error occurs if a semantically valid frame was received on channel B and matches the
all criteria to be appended to the FIFO for channel B but the FIFO is full. In this case, the received frame and its
related slot status information is lost.
0 No such error
1 Receive FIFO overrun on channel B has been detected
Receive FIFO Overrun Channel A Error Flag
— This flag is set when an overrun of the Receive FIFO for
channel A occurred. This error occurs if a semantically valid frame was received on channel A and matches the
all criteria to be appended to the FIFO for channel A but the FIFO is full. In this case, the received frame and its
related slot status information is lost.
0 No such error
1 Receive FIFO overrun on channel B has been detected
Message Buffer Search Error Flag
— This flag is set if the message buffer search engine is still running while
the next search cycle must be started due to the FlexRay protocol timing. In this case, not all message buffers
are considered while searching.
0 No such event
1 Search engine active while search start appears
Message Buffer Utilization Error Flag
— This flag is asserted if the application writes to a message buffer
control field that is beyond the number of utilized message buffers programmed in the
Message Buffer
Segment Size and Utilization Register (MBSSUTR)
.
If the application writes to a MBCCSRn register with n > LAST_MB_UTIL, the FlexRay module ignores the write
attempt and asserts the message buffer utilization error flag MBU_EF in the
CHI Error Flag Register (CHIERFR)
.

0 No such event
1 Non-utilized message buffer enabled
Lock Error Flag
— This flag is set if the application tries to lock a message buffer that is already locked by the
FlexRay module due to internal operations. In that case, the FlexRay module does not grant the lock to the
application. The application must issue the lock request again.
0 No such error
1 Lock error detected
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 FlexRay module 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
