MPC8309 eLBC UPM mode customization.

[avinashpisal]

Hi all,

      I am interfacing MPC8309 eLBC bus with FPGA in UPM mode,timing and functional information provided in reference manual is with respective to DRAM interface,

so would like to know,is it possible to configure UPM mode in simple read/write address and control signals format without DRAM compatible interface.

Thank you.

UPM functionality is not limitted to make DRAM interface only. It is flexible to support various I/O interfaces (SRAM, SSRAM...).
