CBASS routes the transaction to null end point for graceful termination under the following situation:
The null end point returns the error status back to the initiator to prevent the interconnect hang. At the same time, CBASS module logs this transaction information in err_reg region and issues an error interrupt (default_err_intr). This default_err_intr is sent to all the application processors for debug purpose.
If the transaction is sent to a valid target interface, however the firewall in front of the target interface can prohibit the transaction, the transaction will be logged in the glb_regs region and cbass will assert a default_exp interrupt.
