(3) Acceptable commands after serial input command “80h”
(4) Status read during the read operation
(5) Auto program failure
When the serial input command (80h) is input for program execution, commands other than the program execution
command (10h) or reset command (FFh) should not be input.
If a command other than “10h” or “FFh” is input, the program operation is not performed.
When the status read command (70h) is input during reading, the next RE clock signal can be input to read the
value of the internal status register.
Since the internal operation mode is held in Status Read, read data will not be output even if the RE clock signal
is input after becoming ready. Status Read is therefore disabled at reading.
When the read command (00h) is input during the period [A], the internal operation mode of the device can be
canceled, making it possible to read data at address N without inputting Add.

If programming at page address (M) fails, data should be programmed at the
page address (N) of another block.
Data input at first programming at page address (M) will be lost. So address input
using the 80h command must follow the same procedure as data input.
