ADDRESS MODE Operations – Enter and Exit 4-Byte Address Mode
ENTER or EXIT 4-BYTE ADDRESS MODE Command
Both ENTER 4-BYTE ADDRESS MODE and EXIT 4-BYTE ADDRESS MODE commands
share the same requirements.
To enter or exit the 4-byte address mode, the WRITE ENABLE command must be execu-
ted to set the write enable latch bit to 1.
Note: The WRITE ENABLE command is not necessary for line items that enable the ad-
ditional RESET# pin.
S# must be driven LOW. The command must be input on DQn. The effect of the com-
mand is immediate; after the command has been executed, the write enable latch bit is
cleared to 0.
The default address mode is three bytes, and the device returns to the default upon exit-
ing the 4-byte address mode.
ENTER or EXIT QUAD Command
The ENTER or EXIT QUAD (QPI) command is only available for line items that enable
the additional RESET# pin. To initiate this command, the WRITE ENABLE command
must not be executed. S# must be driven LOW, and the command must be input on
DQn. The effect of the command is immediate.
