How to interface the EZ-USB AN21xx to an MCU (generic 8051)?

Question: I would like to interface the EZ-USB AN21xx to an MCU (generic 8051). How can I do this?

 

Answer:

You need to examine the pinout of the MCU and determine what signals you need for data lines, control lines, etc. Then you need to decide if you want to memory map your device (using A[15:0] and D[7:0] on the AN21xx) or use GPIO pins. Please consult the EZ-USB Technical Reference Manual and tutorials for more detailed information.
