depending on the protocol macro processing.
Error Flags for Overrun, Framing, and Parity Errors
When an overrun, framing, or parity error is detected during a protocol macro,
the receive data will be stored in the reception buffer along with error informa-
tion. The error flags will operate as described next.
Receive Data with Error Information that Matches Expected Receive
Messages
The expected receive message received for the RECEIVE operation is found
in the reception buffer and handled as receive data. If the receive data con-
tains error information, the corresponding error flags are turned ON.
The following example shows reception of 100 bytes of data that matches an
expected receive message.
Receive Data with Error Information that Does Not Match Expected
Receive Messages
If there is no expected receive message that matches the receive data, the
data is discarded and the error flags are not affected. The trace information
will contain any error information entering the reception buffer up to the
capacity of the trace data.
The following example illustrated what happens when there is no expected
receive message that matches the receive data.
