Dual Port RAM Controller

The internal 1.5k RAM of the SPC3 is a Single Port RAM. Due to an integrated Dual Port RAM controller, the controller, however, permits an almost simultaneous access of both ports (bus interface and microsequencer interface). When there is a simultaneous access of both ports, the bus interface has priority. This provides for the shortest possible access time. If SPC3 is connected to a microcontroller with an asynchronous interface, SPC3 can evaluate the Ready signal.
