Interconnect 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, the interconnect 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 of the application processors for debug purposes.
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 the interconnect will assert a default_exp interrupt.
