NOTE
: 1. Clock must be stable before exiting self refresh mode. That is, the clock must be cycling within
specifications by Ta0.
2. Device must be in the all banks idle state prior to entering self refresh mode.
3.
t
XSNR is required before any non-READ command can be applied, and
t
XSRD (200 cycles of CK)
is required before a READ command can be applied.
4. AR = AUTO REFRESH command.
