Status Register
The status register shows the operating status of the flash
memory and whether erase operations and programs ended suc-
cessfully or in error. It can be read in the following ways:
(1) By reading an arbitrary address from the User ROM area after
writing the read status register command (70
16
)
(2) By reading an arbitrary address from the User ROM area in the
period from when the program starts or erase operation starts
to when the read array command (FF
16
) is input.
Also, the status register can be cleared by writing the clear status
register command (50
16
).
After reset, the status register is set to
“
80
16
”
.
Table 27 shows the status register. Each bit in this register is ex-
plained below.
Sequencer status (SR7)
The sequencer status indicates the operating status of the flash
memory. This bit is set to
“
0
”
(busy) during write or erase operation
and is set to
“
1
”
when these operations ends.
After power-on, the sequencer status is set to
“
1
”
(ready).
Erase status (SR5)
The erase status indicates the operating status of erase operation.
If an erase error occurs, it is set to
“
1
”
. When the erase status is
cleared, it is set to
“
0
”
.
Program status (SR4)
The program status indicates the operating status of write opera-
tion. When a write error occurs, it is set to
“
1
”
.
The program status is set to
“
0
”
when it is cleared.
If
“
1
”
is written for any of the SR5 and SR4 bits, the program,
erase all blocks, and block erase commands are not accepted.
Before executing these commands, execute the clear status regis-
ter command (50
16
) and clear the status register.
Also, if any commands are not correct, both SR5 and SR4 are set
to
“
1
”
.
