#181792 - Latency Time Problem
Responding to: ???'s previous message
If you were using an external SRAM chip that had power gating to its VDD pin I think there would be a long latency involved with re-powering the SRAM dynamically to get a new seed value. SRAMs such as the old 2Kx8 and 8Kx8 that I've used in the past had quite a long time that they would hold their data at power down. I've seen cases where some or most of the data is retained for times approaching a minute or more.
