10. Command Definitions
Writing specific address and data sequences into the command register initiates device operations.
Table 10.1 on page 38 defines the valid register command sequences. Writing incorrect address and data
values or writing them in the improper sequence may place the device in an unknown state. A hardware reset
may be 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 AC Characteristics on page 48 for timing
diagrams.
10.1
Reading Array Data
The device is automatically set to reading array data after device power-up. No commands are required to
retrieve data. Each bank is ready to read array data after completing an Embedded Program or Embedded
Erase algorithm.
After the device accepts an Erase Suspend command, the corresponding bank enters the erase-suspend-
read mode, after which the system can read data from any non-erase-suspended sector within the same
bank. The system can read array data using the standard read timing, except that if it reads at an address
within erase-suspended sectors, the device outputs status data. After completing a programming operation in
the Erase Suspend mode, the system may once again read array data with the same exception. See Erase
Suspend/Erase Resume Commands on page 37 for more information.
The system must issue the reset command to return a bank to the read (or erase-suspend-read) mode if DQ5
goes high during an active program or erase operation, or if the bank is in the autoselect mode. See Reset
Command on page 32, for more information.
See also Requirements for Reading Array Data on page 15 for more information. Read-Only Operations
on page 48 provides the read parameters, and Figure 17.1 on page 48 shows the timing diagram.
10.2
Reset Command
Writing the reset command resets the banks to the read or erase-suspend-read mode.
The reset command may be written between the sequence cycles in an erase command sequence before
erasing begins. This resets the bank to which the system was writing to the read mode. Once erasure begins,
however, the device ignores reset commands until the operation is complete.
The reset command may be written between the sequence cycles in a program command sequence before
programming begins. This resets the bank to which the system was writing to the read mode. If the program
command sequence is written to a bank that is in the Erase Suspend mode, writing the reset command
returns that bank to the erase-suspend-read mode. Once programming begins, however, the device ignores
reset commands until the operation is complete.
The reset command may be written between the sequence cycles in an autoselect command sequence.
Once in the autoselect mode, the reset command must be written to return to the read mode. If a bank
entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns that bank
to the erase-suspend-read mode.
If DQ5 goes high during a program or erase operation, writing the reset command returns the bank to the
read mode (or erase-suspend-read mode if that bank was in Erase Suspend). Please note that the RY/BY#
signal remains low until this reset is issued.
