DQ3 (Block Erase timer)
The Block Erase operation starts 50
μ
s (the Erase Hold Time) after the rising edge of WE in the last
command cycle. DQ3 outputs a 0 for the duration of the Block Erase Hold Time and a 1 when the Block Erase
operation starts. Additional Block Erase commands can only be accepted during the Block Erase Hold Time.
Each Block Erase command input within the hold time resets the timer, allowing additional blocks to be marked
for erasing. DQ3 outputs a 1 if the Program or Erase operation fails.
DQ2 (Toggle bit 2)
DQ2 is used to indicate which blocks have been selected for Auto Block Erase or to indicate whether the
device is in Erase Suspend Mode.
If data is read continuously from the selected block during an Auto Block Erase, the DQ2 output will toggle.
Now 1 will be output from non-selected blocks; thus, the selected block can be ascertained. If data is read
continuously from the block selected for Auto Block Erase while the device is in Erase Suspend Mode, the DQ2
output will toggle. Because the DQ6 output is not toggling, it can be determined that the device is in Erase
Suspend Mode. If data is read from the address to which data is being written during Erase Suspend in
Programming Mode, DQ2 will output a 1.
