Command Codes and Definitions (Sheet 1 of 2)
Command Set
Device Command Codes
The flash Command User Interface (CUI) provides control of all read, write, and erase
operations. The on-chip WSM manages all block-erase and word-program algorithms.
The flash device commands are written to the CUI to control all flash memory device
operations. The CUI does not occupy an addressable memory location; it is the
mechanism through which the flash device is controlled.

Device Mode
Places the device in Read Array mode. Array data is output on DQ[15:0].
Places the device in Read Status Register mode. The device enters this mode
after a program or erase command is issued. SR data is output on DQ[7:0].
Places device in Read Device Identifier mode. Subsequent reads output
manufacturer/device codes, Configuration Register data, Block Lock status,
or OTP Register data on DQ[15:0].
Places the device in Read Query mode. Subsequent reads output Common
Flash Interface (CFI) on DQ[7:0].
The WSM can only set SR 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 device responds only to Read Status Register and
Program Suspend commands. CE# or OE# must be toggled to update the
Status Register in asynchronous read. CE# or ADV# must be toggled to
update the SR Data for synchronous Non-array reads. The Read Array
command must be issued to read array data after programming has finished.
This command loads a variable number of words up to the buffer size of 512
words into the program buffer.
The confirm command is issued after the data streaming for writing into the
buffer is done. This instructs the WSM to perform the Buffered Program
algorithm, writing the data from the buffer to the flash memory array.
First cycle of a 2-cycle command; initiates the BEFP mode. The CUI then
waits for the BEFP Confirm command, 0xD0, that initiates the BEFP
algorithm. All other commands are ignored when BEFP mode begins.
If the previous command was BEFP Setup (0x80), the CUI latches the
address and data, and prepares the device for BEFP 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 [5,4], and places the
device 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 device responds only to Read Status Register and Erase
Suspend commands. CE# or OE# must be toggled to update the Status
Register in asynchronous read. CE# or ADV# must be toggled to update the
SR Data for synchronous Non-array reads.
