I/O
3
: Sector Erase Timer
After writing a sector erase command sequence, the system
may read I/O
3
to determine whether or not an erase operation
has begun. (The sector erase timer does not apply to the chip
erase command.) If additional sectors are selected for erasure,
the entire time-out also applies after each additional sector
erase command. When the time-out is complete, I/O
3
switches
from "0" to "1." The system may ignore I/O
3
if the system can
guarantee that the time between additional sector erase
commands will always be less than 50
μ
s. See also the "Sector
Erase Command Sequence" section.
After the sector erase command sequence is written, the
system should read the status on I/O
7
(
Data
Polling) or I/O
6
(Toggle Bit I) to ensure the device has accepted the command
sequence, and then read I/O
3
. If I/O
3
is "1", the internally
controlled erase cycle has begun; all further commands (other
than Erase Suspend) are ignored until the erase operation is
complete. If I/O
3
is "0", the device will accept additional sector
erase commands. To ensure the command has been
accepted, the system software should check the status of I/O
3
prior to and following each subsequent sector erase
command. If I/O
3
is high on the second status check, the last
command might not have been accepted. Table 6 shows the
outputs for I/O
3
.

Notes :

toggling. See text.
2. Recheck toggle bit because it may stop toggling as I/O
