DQ1: Write-to-Buffer Abort

DQ1 indicates whether a Write-to-Buffer operation

was aborted. Under these conditions DQ1 produces a

“1”.

The

system

m u st

issue

the

Write-to-Buffer-Abort-Reset command sequence to re-

turn the device to reading array data. See “Write Buffer

Programming” on page 27. for more details.

Table 11.

Write Operation Status

Notes:

1. DQ5 switches to ‘1’ when an Embedded Program, Embedded Erase, or Write-to-Buffer operation has exceeded the

maximum timing limits. See “DQ5: Exceeded Timing Limits” on page 37. for more information.

2. DQ7 and DQ2 require a valid address when reading status information. See “DQ7: Data# Polling” on page 35. and “DQ2: Toggle

Bit II” on page 37 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.
