Re: CodeWarrior 10.5 for Power Arch with QCVS

I'm using the DDR Configuration tool from QCVS to configure for DDR3L.

I'm trying to add config for extended temperature self-refresh (ASR/SRT). My MR2 value (SDRAM_MODE_2) is always zero. Where do I configure for self-refresh?

Also, how is DDR_SDRAM_INTERVAL calculated? My device datasheet (IS46TR16128DL) specifies a refresh interval of 8K cycles. How do I achieve this?

Thanks

In Properties panel in QCVS DDR tool, please click "Advanced" at the right top of the panel, then go to "SDRAM  Mode Configurations"->"SDRAM mode 2(MR2) - DDR SDRAM. Please refer to my screenshot as the following.
