SELF REFRESH
Self-refresh mode is entered by issuing a REFS command (/CS= /RAS= /CAS= L, /WE= H, CKE= L).
Once the self-refresh is initiated, it is maintained as long as CKE is kept low. During the self-refresh mode,
so that power consumption due to synchronous inputs is saved. To exit the self-refresh, supplying stable
CLK inputs, asserting DESEL or NOP command and then asserting CKE (REFSX) for longer than tSRX.
After tRC from REFSX all banks are in the idle state and a new command can be issued, but DESEL or NOP
commands must be asserted till then.
