Updated the EM260 functionality. The original clients were cloned from another client (probably the Chipcon SPI) and were not completely functional for the EM260. The EM260's SPI interface provides direct interaction with the module and the EZSP functionality manages the ZigBee configuration of the chip/module. This is why the original random functionality worked as there was a way to query for random numbers. EZSP, from what I can see, cannot access the chip's flash memory outside of specific tokens. Interaction with the chip/module's firmware/memory have to be performed over the device's proprietary SIF interface. This is an exercise for another day.
