MPC5675K response Transfer Error Acknowledge (TEA)

I have a design using a MPC5675K using the EBI interface.  What is the expected response to a Transfer Error Acknowledge (TEA)?  The BMT value is programmed and the BME bit is set in the EBI_BMCR register.  The processor terminates the error transaction for an externally driven TEA but does not service an exception.  The processor terminates the transaction for an internally driven TEA but continually repeats the transaction until a TA is received.

TEA assertion will behave the same way as expiration of the EBI bus monitor that is DSI or ISI exception (IVOR2 or IVOR3).
