I had to add a clock-enable control to reg 3 of the arbiter. Now it's: [10:0] refresh delay [11] refresh enable [12] clock enable
Here's the startup sequence: - First, cke is already reset to zero - Set cke to 1, refresh enable to zero - Precharge command - Load Extended MR with 15'b01_00000000000_0_0 - Load MR with 15'b00_000010_011_0_001 (I think - must reset the DLL) - Precharge command - Load the refresh counter, with cke and refresh enable set to 1 - Wait 10 microseconds - Load MR with 15'b00_000000_011_0_001 (I think) -- Timothy Normand Miller http://www.cse.ohio-state.edu/~millerti Open Graphics Project _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
