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,
CKE is asynchronous and the only enabled input ,all other inputs including CLK are disabled and ignored,
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.
