Transmit Errors are service-affecting and require a corrective action by the host to resume normal bit-level
processing.
6.4.9.3.1
In the case of underflow due to host ownership of buffer (ONR), sufficient data throughput from shared memory is
not maintained to support the data rate of the serial interface. That is, ownership of messages was not handed over
to MUSYCC in a timely manner.
Reason:
•
28478-DSH-002-E
DMAC reached the end of a buffer by servicing a number of octets equal to the BLEN bit field in a Transmit
Buffer Descriptor. For the transparent mode, EOM is not a valid event because there is no concept of
messages.
MUSYCC writes the Interrupt Descriptor in Interrupt Queue with EVENT = EOB, DIR = 1 (per EOBI in Transmit
Buffer Descriptor).
MUSYCC continues with normal transparent mode processing by processing to the next message structure.
MUSYCC requires more data buffers.
BLP reached the end of a buffer by transferring into shared memory a number of octets equal to the BLEN bit
field in a Receive Buffer Descriptor.
MUSYCC writes the Interrupt Descriptor in Interrupt Queue with EVENT = EOB, DIR = 0 (per EOBI in Receive
Buffer Descriptor).
BLP detects that the serial interface transitions from an out-of-frame to an in-frame condition.
The Interrupt Descriptor in Interrupt Queue with EVENT = FREC, DIR = 0 (per MSKOOF in Group
Configuration Descriptor).
MUSYCC continues with normal transparent mode processing by processing to the next message structure.
