A bus error occurring during a burst fill operation is a special case. If a bus
error occurs during the first cycle of a burst, the data is ignored, the entire
cache line is marked invalid, and the burst operation is aborted. If the cycle
error is processed only if the execution unit attempts to use either of the two
is for an instruction fetch, a bus error exception is made pending. This bus
