Full Status Check
By performing full status check, it is possible to know the execution
results of erase and program operations. Figure 49 shows a full sta-
Fig. 49 Full status check flowchart and remedial procedure for errors
tus check flowchart and the action to be taken when each error oc-
curs.
Read status register
SR4=1 and SR5
=1
NO
YES
SR5=0
YES
Block erase error
NO
SR4=0
YES
NO
Command
sequence error
Program error
End (block erase, program)
Execute the clear status register command (50
16
)
to clear the status register. Try performing the
operation one more time after confirming that the
command is entered correctly.
Should a block erase error occur, the block in error
cannot be used.
Note: When one of SR5 to SR4 is set to
1
, none of the program, erase all blocks,
and block erase commands is accepted. Execute the clear status register
command (50
16
) before executing these commands.
Should a program error occur, the block in error
cannot be used.
