If the processor samples FLUSH# asserted, it writes back any
data cache lines that are in the Modified state and invalidates
all lines in the instruction and data cache. The processor then
drives a flush acknowledge special cycle.
If the processor executes a WBINVD instruction, it drives a
writeback special cycle after the processor completes
invalidating and writing back the cache lines.
