erase operation is complete. If I/O3 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/O3 prior to and following each

subsequent sector erase command. If I/O3 is high on the

second status check, the last command might not have been

accepted. Table 5 shows the outputs for I/O3.
