I have to know how to interface EMIF and external Dpram?

is it EMIF_init function automatically generated address and clock?

how to generate the adress and data on the emif_ pin?

    Hi Prasanna，

    If you use synchronous DPRAM, please use Figure 17-3 and Figure 17-4 to interface the memory. If you use a Async DPRAM, please use Figure 17-7/8/9.

    EMIF_SDRAM_StartupInit() generated by HAlCoGen is used to configure the SDRAM refresh rate, SDRAM timing parameters etc to make the memory interface work properly.

    When you perform data read and write, MCU will generate clock, and toggle address and data pins.

    Regards,
