No-Operation command
(RAS# = "H", CAS# = "H", WE# = "H")
This prevents unwanted commands from being registered during idle or wait states.
The No-Operation command is used to perform a NOP to the SDRAM which is selected (CS# is Low).
10
Burst Stop command
(RAS# = "H", CAS# = "H", WE# = "L")
The Burst Stop command is used to terminate either fixed-length or full-page bursts. This command is
only effective in a read/write burst without the auto precharge function. The terminated read burst ends after a
delay equal to the CAS# latency (refer to the following figure). The termination of a write burst is shown in the
following figure.
