Device
Command
Description
Read
FFh
Read Array
Places selected partition in Read Array mode.
70h
Read Status
Register
Places selected partition in Status Register read mode. After issuing this
command, reading from the partition outputs SR data on DQ[15:0]. A partition
automatically enters this mode after issuing the Program or Erase command.
90h
Read Identifier
Places the selected partition in Read ID mode. Device reads from partition
addresses output manufacturer/device codes, Configuration Register data, block
lock status, or protection register data on DQ[15:0].
98h
CFI Query
Puts the addressed partition in CFI Query mode. Device reads from the partition
addresses output CFI information on DQ[7:0].
50h
Clear Status
Register
The WSM can set the Status Register’s block lock (SR[1]), VPP (SR[3]), program
(SR[4]), and erase (SR[5]) status bits, but it cannot clear them. SR[5:3,1] can
only be cleared by a device reset or through the Clear Status Register command.
Program
40h
Word Program
Setup
This preferred program command’s first cycle prepares the CUI for a program
operation. The second cycle latches address and data, and executes the WSM
program algorithm at this location. Status register updates occur when CE# or
OE# is toggled. A Read Array command is required to read array data after
programming.
10h
Alternate Setup
Equivalent to a Program Setup command (40h).
30h
EFP Setup
This program command activates EFP mode. The first write cycle sets up the
command. If the second cycle is an EFP Confirm command (D0h), subsequent
writes provide program data. All other commands are ignored after EFP mode
begins.
D0h
EFP Confirm
If the first command was EFP Setup (30h), the CUI latches the address and data,
and prepares the device for EFP mode.
Erase
20h
Erase Setup
This command prepares the CUI for Block Erase. The device erases the block
addressed by the Erase Confirm command. If the next command is not Erase
Confirm, the CUI sets Status Register bits SR[5:4] to indicate command
sequence error and places the partition in the read Status Register mode.
D0h
Erase Confirm
If the first command was Erase Setup (20h), the CUI latches address and data,
and erases the block indicated by the erase confirm cycle address. During
program or erase, the partition responds only to Read Status Register, Program
Suspend, and Erase Suspend commands. CE# or OE# toggle updates Status
Register data.
Suspend
B0h
Program
Suspend or
Erase Suspend
This command, issued at any device address, suspends the currently executing
program or erase operation. Status register data indicates the operation was
successfully suspended if SR[2] (program suspend) or SR[6] (erase suspend)
and SR[7] are set. The WSM remains in the suspended state regardless of
control signal states (except RST#).
D0h
Suspend
Resume
This command, issued at any device address, resumes the suspended program
or erase operation.
