	  There are multiple Latency Units corresponding to the many
	  interfaces of the system bus arbiter (both CPU side as well as
	  the peripheral side).
	  To add latency to ALL memory transaction, choose Unit 0, otherwise
	  for finer grainer - interface wise latency, specify a bitmap (1 bit
	  per unit) of all units. e.g. 1,2,12 will be 0x1003

	  Unit  0 - System Arb and Mem Controller
	  Unit  1 - I$ and System Bus
	  Unit  2 - D$ and System Bus
