AGILEX 5 EMIF LPDDR4

Hello,

I have the question about EMIF IP Core.
Does Agilex 5 EMIF (Quartus Pro 26.1) provide any documented or undocumented API to issue LPDDR4 Mode Register Read (MRR) commands after calibration, for example to read MR5 Manufacturer ID?

    Hi

    The Agilex 5 EMIF user guide exposes AXI4 mainband and AXI4-Lite sideband interfaces to the IOSSM, but does not expose a user-programmable MRR/MRW command interface or an API for reading arbitrary LPDDR4 mode registers.
