Test Mode field (A8~A7)
These two bits are used to enter the test mode and must be programmed to "00" in normal operation.

Single Write Mode (A9)
This bit is used to select the write mode. When the BS bit is "0", the Burst-Read-Burst-Write mode is
selected. When the BS bit is "1", the Burst-Read-Single-Write mode is selected.

Note: A10 and A11 should stay “L” during mode set cycle.

No-Operation command
(RAS# = "H", CAS# = "H", WE# = "H")
The No-Operation command is used to perform a NOP to the SDRAM which is selected (CS# is Low).
This prevents unwanted commands from being registered during idle or wait states.
9
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.
