Some parametric limits are subject to
G
Erase All Blocks Command (20
16
/20
16
)
By writing the command code
“
20
16
”
in the first bus cycle and the
confirmation command code
“
20
16
”
in the second bus cycle that
follows, the erase all blocks (erase and erase verify) operation
starts.
Whether the erase all blocks command is terminated can be con-
firmed by reading the status register or the RY/BY signal status .
When the erase all blocks operation starts, the read status regis-
ter mode is entered automatically and the contents of the status
register can be read out at the data I/O pins (DB
0
to DB
7
). The
status register bit 7 (SR7) is set to
“
0
”
at the same time the erase
operation starts and is returned to
“
1
”
upon completion of the
erase operation. In this case, the read status register mode re-
mains active until another command is written.
The RY/BY pin is
“
L
”
during erase operation and
“
H
”
when the
erase operation is completed as is the status register bit 7 (SR7).
At erase all blocks end, erase results can be checked by reading
the status register. For details, refer to the section where the sta-
tus register is detailed.
G
Block Erase Command (20
16
/D0
16
)
By writing the command code
“
20
16
”
in the first bus cycle and the
confirmation command code
“
D0
16
”
in the second bus cycle that
follows to the block address of a flash memory block, the block
erase (erase and erase verify) operation starts.
Whether the block erase operation is completed can be confirmed
by reading the status register or the RY/BY pin state. When the
block erase operation starts, the read status register mode is en-
tered automatically and the contents of the status register can be
read out at the data I/O pins (DB
0
to DB
7
). The status register bit
7 (SR7) is set to
“
0
”
at the same time the block erase operation
starts and is returned to
“
1
”
upon completion of the block erase
operation. In this case, the read status register mode remains ac-
tive until the read array command (FF
16
) is written.
The RY/BY pin is
“
L
”
during block erase operation and
“
H
”
when
the block erase operation is completed as is the status register bit
7 (SR7).
At block erase operation end, erase results can be checked by
reading the status register. For details, refer to the section where
the status register is detailed.
