Clock Stop Mode
Notes:
(High-Z)
CKE must be held HIGH with CK = LOW and CK# = HIGH for the full duration of the
clock stop mode. One clock cycle and at least one NOP or DESELECT is required after
the clock is restarted before a valid command can be issued. Figure 9 on page 21 illus-
trates the clock stop mode.
1. Prior to Ta1, the device is in clock stop mode. To exit, at least one NOP is required before
2. Any valid command is allowed; device is not in clock stop mode.
