RM48L952: How to configure EMIF signals in software

Part Number: RM48L952
Other Parts Discussed in Thread: HALCOGEN

Hi,

I am using RM48L952DZWTT in my design.

I am using EMIF lines to interface with my external MAC device.

I am using 16-bit parallel host bus interface to communicate with my MAC.

For MAC and PHY interface, i am using MII interface.

How should i configure in my software to interface my RM48 and external MAC using EMIF.

Here, ASYNC1,ASYNC2,ASYNC3 are given, which one should i use?

Thanks, Reshma

    HALCOGen uses ASYNC1, ASUNC2, ASYNC3 to represent EMF CS[2], CS[3] and CS[4]. You can use either of them to connect to your MAC controller.

    This should be the signal mapping between EMIF and your MAC controller:

    About the timing parameters, please refer to the datasheet of your MAC controller.
