I'm trying to load wave data points into the SRAM. I can set the shadow registers, ram_update, and read back the values that were entered. I cannot seem to load values into the SRAM.
I'm updating the PAT_STATUS reg to allow write according to pg27 of Rev. A of the datasheet and perform the ram_update. I "attempt" to write the data to the SRAM addresses. I set PAT_STATUS reg to allow read and perform the ram_update. When reading the SRAM addresses they all return 00. The CS pin is toggled appropriately between commands.
Is there something else that I've missed in the datasheet?
