sector erase commands is always less than 50 s. See also the Sector Erase
After the sector erase command sequence is written, the system should read the
status on DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure the device accepted
the command sequence, and then read DQ3. If DQ3 is 1, the internally controlled
erase cycle started; all further commands (other than Erase Suspend) are ig-
nored until the erase operation is complete. If DQ3 is 0, the device accepts

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
DQ5 changes to 1. See text.
