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 must not be executed on the N25Q512A83G1241E
and N25Q512A83G1241F devices.
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 available only on the N25Q512A83G1241E
and N25Q512A83G1241F devices.
To initiate this command, S# must be driven LOW, and the command must be input on
DQn. The effect of the command is immediate.
Note: The WRITE ENABLE command must not be executed before this command.
