Notes :
1. Read toggle bit twice to determine whether or not it is
toggling. See text.
2. Recheck toggle bit because it may stop toggling as I/O

changes to "1". See text.

Figure 4. Toggle Bit Algorithm
(Note 1)
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 1) 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 5 shows the outputs for I/O
3
.
