16-BIT CMOS MICROCOMPUTER
DESCRIPTION
<Flash memory mode>
These are single-chip 16-bit microcomputers designed with high-per-
formance CMOS silicon gate technology, including the internal flash
memory and, being packaged in 64-pin plastic molded QFP or shrink
plastic molded DIP. These microcomputers support the 7900 Series
instruction set, which are enhanced and expanded instruction set
and are upper-compatible with the 7700/7751 Series instruction set.
The CPU of these microcomputers is a 16-bit parallel processor that
can also be switched to perform 8-bit parallel processing. Also, the
bus interface unit of these microcomputers enhances the memory
access efficiency to execute instructions fast. Therefore, these mi-
crocomputers are suitable for office, business, and industrial equip-
ment controller that require high-speed processing of large data.
Also, they are suitable for motor-control equipment since each of
them includes the motor control circuit.

•
Control devices for industrial equipment such as communication
and measuring instruments
For the internal flash memory, single-power-supply programming
and erasure, using a PROM programmer or the control by the cen-
tral processing unit (CPU), is supported. Also, each of these micro-
computers has the memory area dedicated for storing a certain
software which controls programming and erasure (reprogramming
control software). Therefore, on these microcomputers, the program
can easily be changed even after they are mounted on the board.

FLASH MEMORY MODE
This internal flash memory has the boot ROM area storing the repro-
gramming control software for reprogramming in the CPU repro-
gramming mode and flash memory serial I/O mode, as well as the
user ROM area storing a certain control software for the normal op-
eration in the microcomputer mode.
These microcomputers contain the flash memory; and single-power-
supply reprogramming is available to this. These microcomputers
have the following three modes, enabling reading/programming/era-
sure for the flash memory:
• Flash memory parallel I/O mode and Flash memory serial I/O
mode, where the flash memory is handled by using an external pro-
grammer.
Although our reprogramming control firmware for the flash memory
serial I/O mode has been stored into this boot ROM area on ship-
ment, the user-original reprogramming control software which is
more appropriate for the user’s system is reprogrammable into this
area, instead. Note that the reprogramming for the boot ROM area is
enabled only in the flash memory parallel I/O mode.
• CPU reprogramming mode, where the flash memory is handled by
the central processing unit (CPU).
As shown in Figure 4, the flash memory is divided into several
blocks, and erasure per block is possible.

Flash Memory Parallel I/O Mode
User ROM Area and Boot ROM Area
The user ROM area and boot ROM area can be reprogrammed in
the flash memory parallel I/O mode.
The flash memory parallel I/O mode is used to manipulate the inter-
nal flash memory with a parallel programmer. This parallel program-
mer uses the software commands listed in Table 1 to do the flash
memory manipulations, such as read/programming/erase opera-
tions.
The programming and block erase operations can be performed only
to these areas.
The boot ROM area, 8 Kbytes in size, is assigned to addresses
000016–1FFF16, so that programming and block erase operations
can be performed only to this area. (Access to any address out of
this area is prohibited).
Table 1. Software commands (flash memory parallel I/O mode

Read Array
The erasable block in the boot ROM area is only one block, consist-
ing of 8 Kbytes. The reprogramming control firmware to be used in
the flash memory serial I/O mode has been stored to this boot ROM
area on our shipment. Therefore, do not reprogram the boot ROM
area if the user uses the flash memory serial I/O mode.
Do not program to addresses FF9016 to FF9F16 because this area is
the reserved area for the programmer.

Note that, when the boot ROM area is read out from the CPU in the
CPU reprogramming mode, described later, its addresses will be
shifted to E00016—FFFF16.
Addresses FF9016 to FF9F16 are the reserved area for the parallel
programmer. Therefore, when the user uses the flash memory paral-
lel I/O mode, do not program to this area.

Flash Memory Serial I/O Mode
In the flash memory serial I/O mode, addresses, data, and software
commands, which are required to read/program/erase the internal
flash memory, are serially input and output with a fewer pins and the
dedicated serial programmer.
In this mode, being different from the flash memory parallel I/O
mode, the CPU controls reprogramming of the flash memory (using
the CPU reprogramming mode), serial input of the reprogramming
data, etc.
The reprogramming control firmware for the flash memory serial I/O
mode has been stored in the boot ROM area on shipment of the
product from us. Note that, then, the flash memory serial I/O mode
will become unavailable if the boot ROM area has been repro-
grammed in the flash memory parallel I/O mode.
Note that, also, this reprogramming control firmware for the flash
memory serial I/O mode is subject to change.
Figures 5 and 6 show the pin connections in the flash memory serial
I/O mode.
The three pins, SCLK, SDA, and BUSY, are used to input and output
serial data.
The SCLK pin is the input pin of external transfer clocks. The SDA
pin is the I/O pin of transmit and receive data, and its output acts as
the N-channel open-drain output. To the SDA pin, connect an exter-
nal pullup resistor (about 1 kΩ). The BUSY pin is the output pin of the
BUSY flag (CMOS output) and goes “H” during BUSY periods owing
to a certain operation, such as transmit, receive, erase, program-
ming, etc.
Transmit and receive data are serially transferred 8 bits at a time.
In the flash memory serial I/O mode, only the user ROM area can be
reprogrammed; the boot ROM area is not accessible.
Addresses FF9016 to FF9F16 are the reserved area for the serial
programmer. Therefore, when the user uses the flash memory serial
I/O mode, do not program to this area.

CPU Reprogramming Mode
Note that addresses of the boot ROM area depend on the accessing
ways to the boot ROM area, When accessing in the flash memory
parallel I/O mode, these addresses will be shifted to 000016 to
1FFF16. On the other hand, when accessing with the CPU, these ad-
dresses will be shifted to E00016 to FFFF16.
The CPU reprogramming mode is used to perform the operations for
the internal flash memory (reading, programming, erasing) under
control of the CPU.
In this mode, only the user ROM area can be reprogrammed; the
boot ROM area cannot be reprogrammed.
Reset removal with both of the MD0 and MD1 pins held “L” invokes
the normal microcomputer mode, and the CPU operates using the
control software stored in the user ROM area. In this case, the boot
ROM area is not accessible.
The user-original reprogramming control software for the CPU repro-
gramming mode can be stored in either the user ROM area or the
boot ROM area.
Because the CPU cannot read out the flash memory in the CPU re-
programming mode, the above software must be transferred to the
internal RAM in advance to be executed.
Removing reset with the MD0 pin held “L” and the MD1 pin “H”, the
CPU starts its operation using the reprogramming control software
stored in the boot ROM area. This mode is called the boot mode. The
reprogramming control software in the boot ROM area can also re-
program the user ROM area.
Boot Mode
After reset removal, be sure not to change the status at pins MD0
and MD1.
The user-original reprogramming control software for the CPU repro-
gramming mode must be stored into the user ROM area or the boot
ROM area in the flash memory parallel I/O mode in advance. (If this
program has been stored into the boot ROM area, the flash memory
serial I/O mode will become unavailable).

Function overview (CPU reprogramming mode)
The CPU reprogramming mode is available in the single-chip mode,
memory expansion mode, and boot mode to reprogram the user
ROM area only.
chart, and be sure to follow this flowchart. As shown in Note 1 of Fig-
ure 8, before selecting the CPU reprogramming mode, set “0” to the
processor mode register 1’s bit 7 (the internal ROM bus cycle select
bit) and set flag I to “1” to avoid an interrupt request input.
When a watchdog timer interrupt request is generated in the CPU
reprogramming mode, when an input to the RESET pin is “L”, or
when the software reset is performed, the flash memory control cir-
cuit and flash memory control register will be reset.
In the CPU reprogramming mode, the CPU erases, programs, and
reads the internal flash memory by writing software commands. Note
that the user-original reprogramming control software must be trans-
ferred to the internal RAM in advance to be executed.
The CPU reprogramming mode becomes active when “1” is written
into the flash memory control register’s bit 1 (the CPU reprogram-
ming mode select bit) shown in Figure 7, and software commands
become acceptable.
When the flash memory is reset during the erase or programming
operation, this operation is cancelled and the target block’s data will
be invalid. Just before writing a software command related to the
erase/programming operation, be sure to write to the watchdog
timer. In the CPU reprogramming mode, be sure not to use the STP
and WIT instructions.
In the CPU reprogramming mode, software commands and data are
all written to and read from even addresses (Note that address A0 in
byte addresses = “0”.) 16 bits at a time. Therefore, a software com-
mand consisting of 8 bits must be written to an even address; there-
fore, any command written to an odd address will be invalid. Since
the write data at the 2nd cycle of a programming command consists
of 16 bits, this data must be written to even and odd addresses.
The seaquencer in the flash memory controls the erase and pro-
gramming operations. What the status of the seaquencer operation
is and whether the programming or erase operation has been com-
pleted normally or terminated by an error can be examined by read-
ing the flash memory control register.
Figure 7 shows the bit configuration of the flash memory control reg-
ister.
Bit 0 (the RY/BY status bit) is a read-only bit for indicating the sea-
quencer operation. This bit goes to “0” (BUSY) while the automatic
programming/erase operation is active and goes to “1” (READY) dur-
ing the other operations.
Bit 1 serves as the CPU reprogramming mode select bit. Writing of
“1” to this bit selects the CPU reprogramming mode, and software
commands will be acceptable. Because the CPU cannot directly ac-
cess the internal flash memory in the CPU reprogramming mode,
writing to this bit 1 must be performed by the user-original repro-
gramming control software which has been transferred to the inter-
nal RAM in advance. To set bit 1 to “1”, it is necessary to write “0” and
“1” to this bit 1 successively. On the other hand, to clear this bit to “0”,
it is sufficient only to write “0”.
Bit 3 (the flash memory reset bit) resets the control circuit of the in-
ternal flash memory and is used when the CPU reprogramming
mode is terminated or when an abnormal access to the flash
memory happens. Writing of “1” to bit 3 with the CPU reprogramming
mode select bit = “1” preforms the reset operation. To remove the
reset, write “0” to bit 3 after confirming bit 0 (the RY/BY status bit) be-
comes “1”.
Bit 5 serves as the user ROM area select bit and is valid only in the
boot mode. Setting this bit to “1” in the boot mode switches an acces-
sible area from the boot ROM area to the user ROM area. To use the
CPU reprogramming mode in the boot mode, set this bit to “1”. Note
that when the microcomputer is booted up in the user ROM area,
only the user ROM area is accessible and bit 5 is invalid; on the other
hand, when the microcomputer is in the boot mode, bit 5 is valid in-
dependent of the CPU reprogramming mode. To rewrite bit 5, ex-
ecute the user-original reprogramming control software transferred
to the internal RAM in advance.

Software Commands
Table 2 lists the software commands.
Start
By writing a software command after the CPU reprogramming mode
select bit has been set to “1”, erasing, programming, etc. can be
specified. Note that, at software commands’ input, the high-order
byte (D8–D15) is ignored. (Except for the write data at the 2nd cycle
of a programming command.)
Single-chip mode,
Memory expansion mode,
or Boot mode
Software commands are explained as below.
Read Array Command (FF16)
The processor mode register 1 is set (Note 1).
Flag I is set to “1”.
By writing command code “FF16” at the 1st bus cycle, the microcom-
puter enters the read array mode. If an address to be read is input in
the next or the following bus cycles, the contents at the specified ad-
dress are output to the data bus (D0 to D15) in a unit of 16 bits.
The read array mode is maintained until writing of another software
command.
The user-original reprogramming control software
for the CPU reprogramming mode is transferred to
the internal RAM.
Jump to the above software in the internal RAM.
(The operations shown below will be executed by
the above software in this RAM.)
Read Status Register Command (7016)
Writing command code “7016” at the 1st bus cycle outputs the con-
tents of the status register to the data bus (D0-D7) by a read at the
2nd bus cycle.
(Only in the boot mode.)
The user ROM area select bit is set to “1”.
The status register is explained later.
Clear Status Register Command (5016)
This command clears two status bits (SR.4, 5) each of which is set
to “1” to indicate that the operation has been terminated by an error.
To clear these bits, write command code “5016” at the 1st bus cycle.
Writing of “1” to the CPU reprogramming mode select bit.
(Writing of “0” → Writing of “1”)
Programming Command (4016)
Operations such as erasing, programming are
executed by using software commands.
This command facilitates programming of 1 word (2 bytes) at a time.
To initiate programming, write command code “4016” at the 1st bus
cycle; when write data is written in a unit of 16 bits at the 2nd bus
cycle, the address is specified at the same time. Upon completion of
data writing, automatic programming (data programming and verifi-
cation) operation is started.
Read array command is executed, or reset is
performed by setting the flash memory reset bit.
(Writing of “1” → Writing of “0”) (Note 2)
The completion of the automatic programming operation is con-
firmed by a read of the flash memory control register. The RY/BY sta-
tus bit of the flash memory control register goes “0” during the
automatic programming operation; and also, it goes “1” after the
end of it.
Writing of “0” to the CPU reprogramming mode
select bit.
(Only in the boot mode.)
Writing of “0” to user ROM area select bit (Note 3).
Before execution of the next command, be sure to confirm that the
RY/BY status bit is set to “1” (READY). During the automatic pro-
gramming operation, writing of commands and access to the flash
memory must not be performed.
Completed
When programming continuously, the programming command can
be executed with the read status register mode kept if there is no
programming error. Simultaneously with start of the automatic pro-
gramming, the read status register mode is automatically active. In
this case, the read status register mode is retained until the next read
array command (FF16) is written or until the reset is performed by
using the flash memory reset bit.
Notes 1: The processor mode register 1’s bit 7 (address 5F16, the
internal ROM bus cycle select bit) must be “0” (bus cycle
= 3φ).
2: To terminate the CPU reprogramming mode after the
erase and programming operations have been
completed, be sure to execute the read array command
or perform the flash memory reset operation.
3: This bit may remain “1”. However, if this bit is “1”, the
user ROM area access is specified.
Reading out the status register after the automatic programming op-
eration is completed reports the result of it. For details, refer to the
section on the status register.
Figure 9 shows an example of the programming flowchart.
Additional programming to any word that has already been pro-
grammed is prohibited.

3: SRD = Status Register Data
4: WA = Write Address, WD = Write Data (16 bits).
5: Block address: the maximum address of each block must be input. Note that address A0 = “0”.
Block Erase Command (2016/D016)
Writing command code “2016” at the 1st bus cycle and writing confir-
mation command code “D016” and the maximum address of the
block (Note that address A0 = “0”.) at the subsequent 2nd bus cycle
initiate the automatic erase (erasing and erase verification) operation
for the specified block.
The completion of the automatic erase operation is confirmed by a
read of the flash memory control register. The RY/BY status bit of the
flash memory control register goes “0” simultaneously with start of
the automatic erase operation; and also, it goes “1” simultaneously
with completion of it.
Before execution of the next command, be sure to confirm that the
RY/BY status bit is set to “1” (READY). During the automatic erase
operation, writing of commands and access to the flash memory
must not be performed.
Simultaneously with start of the automatic erase, the read status reg-
ister mode is automatically active. In this case, the read status regis-
ter mode is retained until the next read array command (FF16) is
written or until the reset is performed by using the flash memory re-
set bit.
Reading out the status register after the automatic erase operation
is completed reports the result of it. For details, refer to the section
on the status register.
Figure 10 shows an example of the block erase flowchart.

Erase All Block Command (2016/2016)
Writing command code “2016” at the 1st bus cycle and writing com-
mand code “2016” at the subsequent 2nd bus cycle initiate the con-
tinuous block erase (chip erase) operations for all the blocks.
The completion of the chip erase operation, as well as of the block
erase operation, is confirmed by a read of the flash memory control
register. The result of the automatic erase operation is also reported
by a read of the status register.

Erase Status Bit (SR.5)
This bit reports the status of the automatic erase operation. This bit
is set to “1” if an erase error occurs and returns to “0” if the clear sta-
tus register command (5016) is written.
Programming Status Bit (SR.4)
Note that, writing of “FF16” forces the microcomputer into the read
array mode. Simultaneously with this, the command written in the 1st
bus cycle will be canceled.
This bit reports the status of the automatic programming operation.
This bit is set to “1” if a programming error occurs and returns to “0”
if the clear status register command (5016) is written.
Under the condition that any of SR.5, SR.4 = “1”, none of the pro-
gramming, block erase, and erase all block commands can be ac-
cepted. Before execution of these commands, execute the clear
status register command (5016), in advance, to clear these status
bits.
