Enable auto entry and auto exit self-refresh. Configure entry idle time to 16x long count sequences. Where a long count sequence is 1024 cycles. The idle entry configuration is based on 32x of the DLL lock time (512 cycles). A conservative setting to help minimize self-refresh enter/exit thrashing.
