2.3.10 Error responses

AMBA defines external AXI slave error, SLVERR, and external AXI decode error, DECERR. The MMU-600 error response behavior depends on the interface.

The TCU QTW/DVM interface treats SLVERR and DECERR identically, as an abort.

When terminating a transaction, the TBS interface generates a SLVERR response.

If the TBU TBM interface receives a SLVERR or DECERR response to a downstream transaction, it propagates the same abort type to the TBS interface.
