Data

10.10 Write Operation Status
The device provides several bits to determine the status of a program or erase operation: DQ2, DQ3, DQ5,
DQ6, and DQ7. Table 10.5 on page 60 and the following subsections describe the function of these bits. DQ7
and DQ6 each offer a method for determining whether a program or erase operation is complete or in
progress. The device also provides a hardware-based output signal, RY/BY#, to determine whether an
Embedded Program or Erase operation is in progress or is completed.
10.11 DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase algorithm
is in progress or completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising
edge of the final WE# pulse in the command sequence.
During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum
programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the
Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system
must provide the program address to read valid status information on DQ7. If a program address falls within a
protected sector, Data# Polling on DQ7 is active for approximately 1 s, then the device returns to the read
mode.
During the Embedded Erase algorithm, Data# Polling produces a 0 on DQ7. When the Embedded Erase
algorithm is complete, or if the device enters the Erase Suspend mode, Data# Polling produces a 1 on DQ7.
The system must provide an address within any of the sectors selected for erasure to read valid status
information on DQ7.
After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling
on DQ7 is active for approximately 100 s, then the device returns to the read mode. If not all selected
sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the
selected sectors that are protected. However, if the system reads DQ7 at an address within a protected
sector, the status may not be valid.
Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously
with DQ0–DQ6 while Output Enable (OE#) is asserted low. That is, the device may change from providing
status information to valid data on DQ7. Depending on when the system samples the DQ7 output, it may read
the status or valid data. Even if the device completed the program or erase operation and DQ7 has valid data,
the data outputs on DQ0–DQ6 may be still invalid. Valid data on DQ0–DQ7 appears on successive read
cycles.
Table 10.5 on page 60 shows the outputs for Data# Polling on DQ7. Figure 10.5 on page 56 shows the Data#
Polling algorithm. Figure 15.8 on page 69 shows the Data# Polling timing diagram.
