Table 8.

Primary Vendor-Specific Extended Query

COMMAND DEFINITIONS

Writing specific address and data commands or se-

quences into the command register initiates device op-

erations. Tables 10 and 11 define the valid register

command sequences. Writing incorrect address and

data values or writing them in the improper se-

quence may place the device in an unknown state. A

reset command is then required to return the device to

reading array data.

All addresses are latched on the falling edge of WE#

or CE#, whichever happens later. All data is latched on

the rising edge of WE# or CE#, whichever happens

first. Refer to the AC Characteristics section for timing

diagrams.

Reading Array Data

The device is automatically set to reading array data

after device power-up. No commands are required to

retrieve data. The device is ready to read array data

after completing an Embedded Program or Embedded

Erase algorithm.

After the device accepts an Erase Suspend command,

the device enters the erase-suspend-read mode, after
