General Description
Because the A29DL323 enables the boot sector to be
erased, it is ideal for storing a boot program. In addition,
program code that controls the flash memory can be also
stored, and the program code can be programmed or
erased without the need to load it into RAM. Eight small
sectors for storing parameters are provided, each of which
can be erased in 8 Kbytes units.
Once a program or erase command sequence has been
executed, an automatic program or automatic erase
function internally executes program or erase and
verification automatically.
Because the A29DL323 can be electrically erased or
programmed by writing an instruction, data can be
reprogrammed on-board after the flash memory has been
installed in a system, making it suitable for a wide range of
applications.
The A29DL323 is a flash memory organized of 33,554,432
bits and 71 sectors. Sectors of this memory can be erased
at a low voltage (2.7 to 3.6 V) supplied from a single power
source, or the contents of the entire chip can be erased.
Two modes of memory organization, BYTE mode
(4,194,304 words × 8 bits) and WORD mode (2,097,152
words × 16 bits), are selectable so that the memory can be
programmed in byte or word units.
The A29DL323 can be read while its contents are being
erased or programmed. The memory cell is divided into two
banks. While sectors in one bank are being erased or
programmed, data can be read from the other bank thanks
to the simultaneous execution architecture. The banks are
8 Mbits and 24 Mbits.
This flash memory comes in two types. The T type has a
boot sector located at the highest address (sector) and the
B type has a boot sector at the lowest address (sector).

Read Operation
Hardware Reset Pin
The read operation is controlled by the OE and /OE. The
/CE is used to select a device, and the OE controls data
output. The following three access times are used
depending on the condition.
- Address access time (tACC): Time until valid data is
output after an address has been determined
(however, after CE ).
The device is reset to the read mode if VIL is input to the
RESET for the duration of tRP and VIH for the duration of
tRH. While VIL is being input to the RESET , all commands
are ignored, and the output pins go into a Hi-Z state. If the
voltage on RESET is kept to GND ± 0.2 V at this time, the
current consumption can be lowered to 5µA or less. If VIH is
input to the RESET , tREADY is required until data is output.
For the timing waveform, refer to Timing Waveform for
Read Cycle (2).
-
-
CE access time (tCE): Time until valid data is output
after CE has been determined (however, after
address).
OE access time (tOE): Time until valid data is output
Output Disable Mode
Output from the device is disabled (Hi-Z state) if VIH is input
to the OE .
after OE has been determined (however, OE must
be input after tACC-tOE, tCE-tOE after address and CE
have been determined).
On power-up, the device is automatically set in the read
mode. To read the device without changing address
immediately after power application, either execute
hardware reset or briefly lower CE to VIL from VIH.
For the timing waveform, refer to Timing Waveform for
Read Cycle (1).
Sector Group Protection
Protect the sector group by using a command. OE or WE
control is no need.
Temporary Sector Group Unprotect
Protection of a sector group can be temporarily canceled.
When VID is input to RESET , the temporary sector group
unprotect mode is set. If a protected sector is selected in
this mode, it can be programmed or erased. If the mode is
canceled, the sector group is protected again.
For the timing waveform, refer to Timing Waveform for
Temporary Sector Group Unprotect.
Write Operation
The operation of the device is controlled by writing
commands to the registers. The command register is a
function that latches the address and data necessary for
executing an instruction and does not occupy the memory
area.
If an illegal address or data is written or if an address or
data is written in the wrong sequence, the device is reset to
the read mode.
Product ID
Read the product ID code by using a command.
Standby Mode
Automatic Sleep Mode
The standby mode is set when VIH is input to the CE . The
current consumption in the standby mode can be lowered to
5 µA or less in two ways.
One is to use CE and RESET . Input VCC ± 0.3 V to CE
and RESET . However, while automatic programming or
erasing is being executed, the operating supply current
(ICC2) does not decrease to 5µA or lower even if CE = VIH.
If a read operation is executed in the standby mode, data is
output at CE access time.
The other is to input GND ± 0.3 V to the RESET . At this
The automatic sleep mode is used to reduce the power
consumption substantially during a read operation.
If an address is held longer than the minimum read
cycle time (tRC), the sleep mode (low power
consumption mode) is automatically set. In this mode, the
output data is latched and continuously output.
In the automatic sleep mode, CE , WE , and OE do not
have to be controlled. At this time, the current consumption
decreases to 5µA or less. During dual operation,
however, the current consumption is power supply
current (ICC6, ICC7).
If the address is changed, the automatic sleep mode
is canceled automatically, the device returns to the
read mode, and the data of the newly input address is
output.
time, the level of CE is VIH or VIL. In this case, tRH is
required for the device to return to the read mode from the
standby mode.
For the timing waveform, refer to Timing Waveform for
Read Cycle (2).

In the accelerated mode, protection of the sector group is
temporarily canceled. Exercise care in programming the
device at this time.
For the timing waveform, refer to Timing Waveform for
Accelerated Mode.
Boot Block Sector Protect
The boot block sector protect mode protects the two sectors
of the boot block. This mode is set when VIL is input to WP
(ACC). If VIL is input to WP (ACC) even in the temporary
sector group unprotect mode, the boot block remains
protected and protection of the other sectors is temporarily
canceled.
Dual Operation
This device can execute a program or erase operation and
a read operation simultaneously. By selecting bank 1 or 2
by changing the bank address, one bank can execute a
read operation while the other bank is executing a program
or erase operation. When changing the bank address, no
wait cycle is necessary. Note that two or more program or
erase operation. When changing the bank address, no wait
cycle is necessary. Note that two or more operations cannot
be executed at the same time in the same bank.
The following table shows the combinations of bank
operations.
For the timing waveform, refer to Timing Waveform for Dual
Operation.
Accelerated Mode
This mode is used to program the device at high speed,
and the programming time can be shortened to about 60%.
To program the device in the accelerated mode, input
VACC to WP (ACC) and use an unlock bypass program
command. Therefore, ordinary commands can be used for
programming or detection of completion of programming.
If VACC is input to WP (ACC), the device is automatically
set in the unlock bypass mode. Therefore, the unlock
bypass set command and reset command are not
necessary. The accelerated mode is automatically canceled
if the input of VACC to WP (ACC) is stopped.

Sector Group Protection
Query
This command performs sector group protection.
By applying VID to RESET and writing 60H to any address,
the device enters the sector group protection mode.
Sector group protection is started by inputting the sector
group address of the sector group to be protected to A12 to
A20, inputting (A6, A1, A0) = (VIL, VIH, VIL), and writing 60H.
After a timeout of 250µs, sector group protection is
completed.
Next, with the sector group address input to A12 to A20, the
device enters the sector group protection verify mode by
inputting (A6, A1, A0) = (VIL, VIH, VIL), and writing 40H. When
read is performed in this state, the sector group protection
verify result is output to I/O0. If "1" is output to I/O0, the
verified sector group is protected. If "1" was not output to
I/O0, sector group protection failed, so perform sector group
protection again.
For the timing waveform and flow chart, refer to Timing
Waveform for Sector Group Protection and Figure 1.
The dual operation flash memory conforms to CFI (Common
Flash memory Interface). CFI enables information about a
device such as the device specifications, memory density,
and supply voltage to be read. Therefore, the software of the
host system can support the software algorithm of a specific
vendor used by a device by using the CFI. For details, refer
to the CFI specifications.
By writing the Query command (98H) and giving an address,
the device information corresponding to that address can be
read. If the device information is read in the WORD mode
(16 bits), the upper bytes of data (I/O15 to I/O8) are "0".
To end the Query mode, writes the read / reset command.
Extra One Time Protect Sector Entry
The dual operation flash memory has a sector area that has
One Time Protect function. This area does not allow code
that has been written to the area to be changed. This area
can be programmed or erased until it is protected.
Once it has been protected, however, protection can never
be canceled. Therefore, care must be exercised when using
this area.
The Extra One Time Protect Sector area has a density of 64
Kbytes and exits at the same addresses as the 8 Kbytes
sector. These addresses are 3F0000H to 3FFFFFH for top
boot in the BYTE mode (1F8000H to 1FFFFFH in the WORD
mode), and 000000H to 00FFFFH for bottom boot in the
BYTE mode (000000H to 007FFFH in the WORD mode).
Because boot block areas (8 Kbytes x 8 sectors) usually
appear in the areas of these addresses, the Extra One Time
Protect Sector entry command sequence must be written to
enter them as the Extra One Time Protect Sector area. The
status in which the Extra One Time Protect Sector area
appears is the Extra One Time Protect Sector mode.
In the Extra One Time Protect Sector mode, the other
sectors, except the boot block area, can be read. In addition,
the Extra One Time Protect Sector area can be read,
programmed, or erased in this mode. To exit from the Extra
One Time Protect Sector mode, the Extra One Time Protect
Sector Reset command sequence must be written.
Sector Group Unprotect
This command performs sector group unprotect.
Sector group unprotect is performed for all sector group.
Unprotect cannot be performed for specific sector group.
Moreover, all sector groups must be protected priors to
unprotect.
The device enters the sector group unprotect mode by
applying VID to RESET and writing 60H to any address.
If unprotected sector group exist, first perform sector group
protection for these sector groups. To protect a sector group,
input the sector group address of the sector group to be
protected to the sector group address input pin, input (A6,
A1, A0) = (VIL, VIH, VIL), and write 60H (refer to Sector Group
Protection).
Sector group unprotect is started by inputting (A6, A1, A0) =
(VIH, VIH, VIL), and writing 60H to any address.
Following a timeout of 15 ms, sector group unprotect is
completed.
Unprotect verification must be performed for each sector
group.
The device enters the sector group unprotect verification
mode by inputting the sector group address to input pin of
sector group address and writing 40H, with input (A6, A1, A0)
= (VIH, VIH, VIL).
If reading is performed in this state, the sector group
unprotect verification result is output to I/O0. If the verified
sector group is unprotected, "0" is output to I/O0. If "0" is not
output to I/O0, this means that unprotect failed, so perform
sector group unprotect again.
For the flow chart, refer to Figure 2. Sector Group Unprotect
Flow Chart.

(May, 2002, Version 0.0)
Extra One Time Protect Sector Program
To program data to the Extra One Time Protect Sector area,
write the Extra One Time Protect Sector Program command
sequence in the Extra One Time Protect Sector mode. This
command is no different from the conventional program
command except that it must be written in the Extra One
Time Protect Sector mode. Therefore, completion of
execution of this command is detected in the same manner
as the conventional detection method of using I/O7 data
polling, I/O6 toggle bit, and RY/ BY . Care must be exercised
in selecting a program destination address. If a program
destination address other than the one in the Extra One Time
Protect Sector area is selected, the data of that address is
changed.

Extra One Time Protect Sector Erase
Hardware Data Protection
To erase the Extra One Time Protect Sector area, write the
Extra One Time Protect Sector erase command sequence in
the Extra One Time Protect Sector mode. This command is
the same as the conventional sector erase command except
that it must be written in the Extra One Time Protect Sector
mode. Therefore, completion of execution of this command is
detected in the same manner as the conventional detection
method of using I/O7 data polling, I/O6 toggle bit, and
RY/ BY . Care must be exercised in selecting a sector
address to erase. If a sector address other than the one in
the Extra One Time Protect Sector area is selected, the data
of that sector is changed.
This device requires two unlock cycles for program / erase
command sequence to prevent illegal program / erase.
Moreover, a hardware data protect function is provided as
follows.
Low VCC Write Inhibit
To prevent an illegal write cycle during VCC transition, the
command register and program / erase circuit is disabled and
all write cycles are ignored while VCC is VLKO or lower. Write
commands are ignored until VCC becomes equal to or
greater than VLKO.
Logical Inhibit
Extra One Time Protect Sector Protection
The write cycle is inhibited under any of the following
conditions : OE = VIL, CE = VIH, or WE = VIH. To start a
write cycle, CE = VIL and WE = VIL must be set while /OE =
VIH.
The following write operations are used to protect the Extra
One Time Protect area during the Extra One Time Protect
Sector mode.
Write the sector group protection setup command (60H) in
the Extra One Time Protect Sector mode.
. Set (A6, A1, A0) = (VIL, VIH, VIL), and set the sector address
that selects the Extra One Time Protect Sector.
. Write the sector group protection command (60H).
Because the sequence is the same as the conventional
command sequence to protect a sector group except that the
Extra One Time Protect Sector mode must be set and that
VID is not input to the RESET , the same command
sequence can be used.
For details of how to protect a sector group, refer to Sector
Group Protection.
If an address other than the one of the Extra One Time
Protect Sector area is specified as a sector address, the
other sectors are affected. Once the sector has been
protected, protection can never be canceled. Exercise utmost
care when protecting a sector.
PRELIMINARY
(May, 2002, Version 0.0)
Power-Up Write Inhibit
Even if WE = CE = VIL and OE = VIH are satisfied at
power-up, no commands are accepted at the rising edge of
WE . The device is automatically reset to the read mode at
power ON.
Write Pulse "Glitch" Protection
Because OE , CE , and /WE reject a noise pulse of 5 ns
(typical) or less as an invalid pulse, a write operation is not
started.
Sector Group Protection
The dual operation flash memory can be protected by the
user in sector group units. For details, refer to Sector Group
Protection.

Command Definitions
Writing Commands
All operations are executed by writing a command.
To write a command, the write cycle of a standard
microprocessor is used.
The operation of the device is controlled by writing a
command to a register. The command register is a function
that latches the address and data necessary for executing an
instruction and does not occupy the memory area.
If an illegal address or data is written or if an address or data
is written in the wrong sequence, the device is reset to the
read mode.
Table 8. shows the commands and command sequences.
Read / Reset Command
This command resets the device to the read mode.
The read mode is maintained until the contents of the
command register are changed.
Once the device is in the read mode, no command is
necessary for reading data. Data read can be performed
using the read cycle of a standard microprocessor.
The read mode is maintained until the contents of the
command register are changed.
Following write by command sequence, the pulse required for
program is automatically generated inside the device and
program verification is automatically performed, so that
control from external is not required.
During automatic program, any command other than the
program suspend is ignored. However, automatic program is
interrupted when hardware reset is performed. Since the
programmed data is not guaranteed in this case, reexecute
the program command following completion of reset.
Upon completion of automatic program, the device returns to
the read mode.
The operation status of automatic program can be determined
by using the hardware sequence flags (I/O7, I/O6, RY/ BY
pins).
See sections “I/O7 (Data Polling)”, “I/O6 (Toggle Bit)”, and
“RY/ BY (Ready / Busy )”.
For the timing waveform and flow chart, refer to Timing
Waveform for Write Cycle ( WE Controlled), Timing
Waveform for Write Cycle ( CE Controlled) and Figure 3.
START
Product ID
The manufacturer code and device code can be read without
inputting a high voltage to the address pin.
If a bank address is specified in the third bus cycle and a read
operation is started from address xx00H in the fourth bus
cycle, manufacturer code 10H is output. If address xx02H
(BYTE mode) or xx01H (WORD mode) is read, the device
code is output. If a read operation is executed from an
address in the bank not specified in the third bus cycle, data
of the memory cell is output.
If a read operation is executed starting from address (BA)
02H (WORD mode) or (BA) 04H (BYTE mode), information
indicating which sector group is protected can be obtained. If
the sector group address is scanned with (A6, A1, A0) = (VIL,
VIH, VIL), "1" is output to I/O0 to indicate that the sector group
is protected (for details refer to Sector Group Protection).
The product ID can be read only from the specified bank. To
read the manufacturer code, device code, and information on
protection of sector group from a bank not specified, write the
read / reset command, specify the bank address to be read,
and then write the product ID command again. To end the
product ID mode, writes the read / reset command. To write
the product ID command in the product ID mode, execute the
read / reset command once.

Program Command Sequence
This command is used to program data.
Program is performed in 1 byte or 1 word units. Program can
be performed regardless of the address sequence, even if the
sector limit is exceeded. However, "0" cannot be changed
back into "1" through the program operation. If overwriting "1"
to "0" is attempted, the program operation is interrupted and
"1" is output to I/O5, or successful program is indicated in data
polling, but actually the data is "0" as before.

Program Suspend / Resume Commands
This command is used to suspend automatic programming.
Addresses not being programmed to while programming is
suspended can be read.
Sector erase (including the timeout period) and data program
operations can be both suspended. Chip erase operations
cannot be suspended.
1µs is required between when the command sequence is
programmed and when the automatic program operation is
suspended.
The execution status of an automatic program operation can
be determined using a hardware sequence flag (I/O7, I/O6
pins.) refer to I/O7 (Data polling) and I/O6 (Toggle Bit).
To resume an automatic program operation, write the resume
command (30H) while the operation is suspended.
Caution about Program Suspend / Resume Commands
If automatic program resume and suspend are repeated at
intervals of less than 5µs, the program operation may not be
correctly completed.
Chip Erase Command Sequence
This command is used to erase the entire chip.
Following command sequence write, erase is performed
after "0" is written to all memory cells and verification is
performed, using the automatic erase function. Program
before erase and control from external are not required.
During automatic erase, all commands that have been
written are ignored.
However, automatic erase is
interrupted by hardware reset. Since erase is not
guaranteed in this case, execute the chip erase
command again after reset is completed.
Upon completion of automatic erase, the device returns
to read mode.
The automatic erase operation status can be determined
with the hardware sequence flags (I/O7, I/O6, RY/ BY
pins). See sections “I/O7 (Data Polling)”, “I/O6 (Toggle Bit)”,
and “RY/ BY (Ready / Busy )”.
For the timing waveform and flow chart, refer to Timing
Waveform for Sector / Chip Erase and Figure 4.
timeout period. In this case, the timeout period starts again
after the last erase command has been written.
If a protected sector and a sector that is not protected are
included in the selected sectors, only the sector that is not
protected is erased and the protected sector is ignored.
If a command other than the sector erase or erase suspend
command is input during the timeout period, the device is reset
to the read mode. If the timeout period has elapsed and erase
has started, any command other than the erase suspend
command is ignored. However, erase is stopped if hardware
reset is executed. In this case, sector erase is not guaranteed.
Execute the sector erase command again after completion of
reset.
When automatic erasure has been completed, the device
returns to the read mode.
Completion of automatic sector erase can be reported to the
host system by using the data polling function of I/O7, toggle
bit function of I/O6, and RY/ BY pin. Sector erase is started
after the lapse of the timeout period that is started from the
rising of the WE or CE pulse, whichever earlier, of the last
sector erase command and is completed when the data of I/O7
is set to "1" (refer to Hardware Sequence Flags). The device
returns to the read mode. Data polling and toggle bit function
in any address of the sector that is to be erased. The time
required to erase two or more sectors is "(sector programming
time + sector erase time) x number of sectors". If two or more
sectors of different banks are erased, a read operation from a
bank (i.e., dual operation) cannot be executed.
For the timing waveform and flow chart, refer to Timing
Waveform for Sector / Chip Erase and Figure 4.

Sector Erase Command Sequence
This command is used to erase data in sector units.
"0" is written to the entire sector whose data is to be erased by
the automatic erase function after the command sequence has
been written, and erase is executed after verification has been
performed. Programming before erase and external control are
not necessary.
The timeout period of sector erase starts when erase
command 30H and the address of the sector to be erased are
written at the sixth bus cycle. When this timeout period (50µs)
has elapsed, the device automatically starts erasing.
Two or more sectors can be selected and erased at the same
time by additionally writing erase command 30H and the

Sector Erase Suspend / Resume Commands
This command suspends automatic erase. During erase
suspend, sectors for which erase is not performed can be read
and programmed.
Sector erase (including the timeout period) and data program
operations can be both be suspended. Chip erase operations
cannot be suspended. Suspend can be performed for all
sectors for which erase is being performed.
Following command sequence write, 20µs are required until
automatic erase is suspended.
While automatic erase is suspended, any sector for which
erase is not being performed can be read and programmed.
Whether automatic erase is suspended can be determined
with the hardware sequence flags (I/O7, I/O6, I/O2 pins). See
sections “I/O7 (Data Polling)”, “I/O6 (Toggle Bit)”, and “I/O2
(Toggle Bit II)".
If resume automatic erase that has been suspended, write the

Normally, 4 write cycle included with 2 unlock cycles are
required during program. In contrast, with the unlock bypass
mode, it is possible to perform program without unlock cycles.
In the unlock bypass mode, all commands except unlock
bypass program and unlock bypass reset are ignored.
To end the unlock bypass mode, the unlock bypass reset
command must be written. Note, however, that the unlock

read after automatic program / erase is complete or when it
is suspended, the I/O6 toggle operation is stopped, and valid
data for the read is output. If a sector for which erasure is
suspended is read, “1” will be output to I/O6. Continuous
read control is performed with the OE or CE .
If program is performed for an address inside a protected
sector, I/O6 is toggled approximately 1µs, and then the
device is reset to the read mode.
Moreover, if all the sectors selected at the time of automatic
erase are protected, I/O6 is toggled approximately 400µs,
and then the device is reset to the read mode.
In this way, by using I/O6, it is possible to determine the
status of automatic erase is in progress (or suspended), but
to determine which sector is being erased, I/O2 (Toggle Bit
II) is used. See section “I/O2 (Toggle Bit II)”.
For the timing waveform and flow chart, refer to Timing
Waveform for Toggle Bit, Timing Waveform for I/O2 vs. I/O6
and Figure 7.
Hardware Sequence Flags
The status of automatic program / erase operations can be
determined from the status of the I/O2, I/O3, I/O5, I/O6,
I/O7, and RY / BY pins.
Caution When Reading Flags
When checking the completion or suspension status of an
automatic program / erase operation by reading different
sector data within the same bank, be sure to either clock
the CE or change the address before reading the data.
If the CE is fixed to VIL or data is read from the same
address without the address being changed, the output
data may not be output correctly.
I/O7 : Data Polling
Data polling is a function to determine the status of
automatic program / erase is currently being performed by
using I/O7.
Data polling is valid from the rise of the last WE in the
program / erase command sequence.
The status of automatic program is currently being
executed can be determined by reading from the program
destination addresses. While automatic programming is
being executed or while automatic programming is being
executed during erasure suspension, the complement of
the final data programmed will be output to I/O7. Upon
completion of automatic program, the true value of the
programmed data, not the complement, is output.
The status of automatic erase is in progress can be
determined by reading from the addresses of the sector
being erased. If erase is in progress, "0" is output to I/O7. If
the automatic erase operation is complete or if it is
suspend, "1" will be output to I/O7 when a sector for which
erasure is suspended is read.
During automatic erase, if all the selected sectors are
protected, data polling is valid for approximately 400µs.
The device is then reset to the read mode. If the selected
sectors include protected and unprotected sectors, only
unprotected sectors are erased, and protected sectors are
ignored.
Upon completion of automatic program / erase, after the
data output to I/O7 changes from the complement to the
true value, I/O7 changes asynchronously like I/O0 to I/O6
while OE is maintained at low level.
For the timing waveform and flow chart, refer to Timing
Waveform for Data Polling and Figure 6.

I/O6 : Toggle Bit
Figure 6. Data Polling Flow Chart
The toggle bit is a function that uses I/O6 to determine the
status of automatic program / erase is in progress.
The toggle bit is valid from the rise of the last WE in the
program / erase command sequence.
If a continuous read is performed from any address of a
bank that is undergoing automatic program or erase, I/O6
will be toggled. If a sector other than the erased sector is

I/O2: Toggle Bit II
RY BY : Read/ Busy
Toggle bit II is a function that determines the status of
automatic erase (or erase suspend) is in progress for a
particular sector by using I/O2.
I/O2 is toggled when continuous read is performed from
addresses in a sector during automatic erase (or erase
suspend). Either OE or CE is used to control continuous
read.
When program to a sector that is not subject to erase
suspend is attempted during erase suspend, read from
sectors that are not subject to erase suspend cannot be
performed until program is completed. In this case, "1" will
be output to I/O2 if a continuous read is performed from an
address in a sector other than an erased sector.
In this way, it is possible to determine the status of
automatic erase (including erase suspend) is in progress for
sectors specified using I/O2, but whether the state is erase in
progress or erase suspend cannot be determined with I/O2.
To determine this, I/O6 (Toggle Bit) must be used. See
section “I/O6 (Toggle Bit)”.
For the timing waveform, refer to Timing Waveform for I/O2
vs. I/O6.
The RY/ BY is a dedicated output pin used to check the
status of automatic program / erase is in progress.
During automatic program / erase, "0" is output to the RY
/ BY . If "1" is output, this signifies that the device is either in
the read mode (including erase suspend) or standby mode.
Since the RY/ BY is an open-drain output pin, it is possible
to connect several RY/ BY in series by connecting a pull-up
resistor to VCC.
For the timing waveform, refer to Timing Waveform for
RY/ BY (Ready / Busy ).

I/O5 : Exceeding Timing Limits
If the program / erase time exceeds the prescribed number
of pulses during automatic program / erase (exceeding
timing limit), "1" is output to I/O5 and automatic program /
erase failure is indicated.
Moreover, if overwriting "0" to "1" is attempted, the device
judges data overwrite to be impossible, and "1" is output to
I/O5 when the timing limit is exceeded.
When this happens, execute command reset.

I/O3 : Sector Erase Timer
(May, 2002, Version 0.0)
Read (I/O0 to I/O 7)
An=Any Address in the Bank Being Executed
I/O7=Toggle?
A 50µs timeout period occurs following write with the sector
erase command sequence before automatic erase starts.
During this timeout period, "0" is output to I/O3. When
automatic erase starts upon completion of the timeout
period, "1" is output to I/O3.
If sector erase is performed, first confirm whether the device
has received a command by using I/O7 (Data Polling) or I/O6
(Toggle Bit). Then, using I/O3, check whether automatic
erase has started. If I/O3 is "0", the timeout period is not
over, and so it is possible to add sectors to erase. If I/O3 is
"1", automatic erase starts and other commands (except
erase suspend) are ignored until erase is completed.
If a sector to erase is added during the sector erase timeout
period, it is recommended to check I/O3 prior to and
following the addition. If I/O3 is "1" following the addition,
that addition may not be accepted.
