COMMAND
The clock suspend mode occurs when a column access/burst is in progress and CKE is
registered LOW. In the clock suspend mode, the internal clock is deactivated, “freezing”
the synchronous logic.
For each positive clock edge on which CKE is sampled LOW, the next internal positive
clock edge is suspended. Any command or data present on the input pins at the time of a
suspended internal clock edge is ignored; any data present on the DQ pins remains
driven; and burst counters are not incremented, as long as the clock is suspended (see
examples in Figures 25 and 26 on page 35).
