| 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 |
