DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count limit.
Under these conditions DQ5 produces a “1,” indicating that the program or erase cycle was not
successfully completed. The device does not output a 1 on DQ5 if the system tries to program a 1 to a
location that was previously programmed to 0. Only an erase operation can change a 0 back to a 1.
Under this condition, the device ignores the bit that was incorrectly instructed to be programmed from a
0 to a 1, while any other bits that were correctly requested to be changed from 1 to 0 are programmed.
Attempting to program a 0 to a 1 is masked during the programming operation. Under valid DQ5
conditions, the system must write the reset command to return to the read mode (or to the erase-
suspend-read mode if a sector was previously in the erase-suspend-program mode).
DQ3: Sector Erase Timeout State Indicator
After writing a sector erase command sequence, the output on DQ3 can be checked to determine
whether or not an erase operation has begun. (The sector erase timer does not apply to the chip erase
command.) When sector erase starts, DQ3 switches from “0” to “1”. This device does not support
multiple sector erase (continuous sector erase) command sequences so it is not very meaningful since
it immediately shows as a “1” after the first 30h command. Future devices may support this feature.
DQ1: Write to Buffer Abort
DQ1 indicates whether a Write to Buffer operation was aborted. Under these conditions DQ1 produces
a “1”. The system must issue the “Write to Buffer Abort Reset” command sequence to return the device
to reading array data.

Notes
1. DQ5 switches to 1 when an Embedded Program, Embedded Erase, or Write-to-Buffer operation has
exceeded the maximum timing limits.
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate
subsection for further details.
3. The Data# Polling algorithm should be used to monitor the last loaded write-buffer address location.
4. DQ1 switches to 1 when the device has aborted the write-to-buffer operation
Writing Commands/Command Sequences
During a write operation, the system must drive CE# and WE# to VIL and OE# to VIH when providing
an address, command, and data. Addresses are latched on the last falling edge of WE# or CE#, while
data is latched on the 1st rising edge of WE# or CE#. An erase operation can erase one sector or the
