A microprocessor including a cache memory and bus interface logic. The bus interface logic is interfaced with request signals and data signals and includes a request interface and a response interface. The request interface provides a request via the request signals for a data transaction in which the request specifies a selected burst order. The response interface stores data received via the data signals into the cache memory according to the selected burst order. The request interface may specify the selected burst order by configuring a field of a request packet during a request phase of the data transaction. The selected burst order may selected from any of several different data transaction orderings, including an interleaved order, a linear order, a nibble linear order and a custom order. The microprocessor may further include instruction logic which provides an instruction to the bus interface logic specifying the selected burst order.
