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 .. Unit 12 - IDE Disk controller and System Bus
