Device Mode
Places the addressed partition in Read Array mode. Array data is output on
AD[15:0].
Places the addressed partition in Read Status Register mode. The partition enters
this mode after a program or erase command is issued. Status Register data is
output on AD[7:0].
Places the addressed partition in Read Device Identifier mode. Subsequent reads
from addresses within the partition outputs manufacturer/device codes,
Configuration Register data, Block Lock status, or Protection Register data on
AD[15:0].
Places the addressed partition in Read Query mode. Subsequent reads from the
partition addresses output Common Flash Interface information on AD[7:0].
The WSM can only set Status Register error bits. The Clear Status Register
command is used to clear the SR error bits.
First cycle of a 2-cycle programming command; prepares the CUI for a write
operation. On the next write cycle, the address and data are latched and the WSM
executes the programming algorithm at the addressed location. During program
operations, the partition responds only to Read Status Register and Program
Suspend commands. In asynchronous mode the falling edge of OE#, or CE#
(whichever occurs first) updates and latches the Status Register contents.
However, reading the Status Register in synchronous burst mode, CE# or ADV#
must be toggled to update status data. The Read Array command must be issued
to read array data after programming has finished.
Equivalent to the Word Program Setup command, 0x40.
First cycle of a 2-cycle command; prepares the device to receive a variable
number of bytes up to the write buffer size of 32 words. The second cycle
contains the number of bytes to be transferred.
Issued after writing all data to the write buffer; instructs the WSM to perform its
Buffered Programming algorithm, writing the data from the write buffer to the
flash memory array.
First cycle of a 2-cycle command; initiates Buffered Enhanced Factory Program
mode (Buffered EFP). The CUI then waits for the Buffered EFP Confirm command,
0xD0, that initiates the Buffered EFP algorithm. All other commands are ignored
when Buffered EFP mode begins.
If the previous command was Buffered EFP Setup (0x80), the CUI latches the
address and data, and prepares the device for Buffered EFP mode.
First cycle of a 2-cycle command; prepares the CUI for a block-erase operation.
The WSM performs the erase algorithm on the block addressed by the Erase
Confirm command. If the next command is not the Erase Confirm (0xD0)
command, the CUI sets Status Register bits SR[4] and SR[5], and places the
addressed partition in read status register mode.
If the first command was Block Erase Setup (0x20), the CUI latches the address
and data, and the WSM erases the addressed block. During block-erase
operations, the partition responds only to Read Status Register and Erase
Suspend commands.
This command issued to any device address initiates a suspend of the currently-
executing program or block erase operation. The Status Register indicates
successful suspend operation by setting either SR[2] (program suspended) or
SR[6] (erase suspended), along with SR[7] (ready). The Write State Machine
remains in the suspend mode regardless of control signal states (except for RST#
asserted).
This command issued to any device address resumes the suspended program or
block-erase operation.
