NEe NEe Microcomputers, Inc. ",PD3301-1 ",PD3301-2 ~m~[~~~~illmW PROGRAMMABLE CRT CONTROLLER DESC RIPT ION The IlPD3301 is an LSI chip designed for use in CRT controllers. It contains a synchronous signal generator. row buffer. and attribute memory. This CRT controller is capable of handling not only black and white CRT. but also color CRT. The IlPD3301 provides control signals which simplify the design of the external circuitry needed in the systems. Thus, this device is a versatile controller that relieves the main CPU (and users) of many of the control burdens associated with implementing a CRT interface. There are 8 separate commands which the IlPD3301 will execute.
