Chapter 1Introduction
This user manual introduces the ELAN Display WRITER’s hardware, PC software for
window version , and how to use it. Display WRITER is a very user-friendly and highly portable
programmer used to program the all 8-bit family OTP (One Time Programmable) EM78P153S/
P156E/ P156N/ P257/ P447S/ P447N/ P451/ P451S/ P458/ P459/ P468N microcontrollers and
other EM78 family’s OTP microcontrollers in the future. It communicates with IBM PCs or
compatibles through a printer port. Moreover, the window version software ELAN supplies is
very easy to use and is available either in the compact disk or on the ELAN’s website. Due to
the result of its fast and accurate programming, the writer is quite suitable for pilot run, and
mass production as well.

 Power indicator The LCM is on as power is supplied to the writer.
 Program Indication  General function: If using internal RC oscillator mode,
there will be the IRC frequency displayed on the LCM as
DWTR works alone.
 Programming Counter function. This function will be active
if users keep pressing the red button for three seconds.
The LCM will switch to the programming counter function
page for five seconds as users release the red button and
will then return back to the general function page.
 LCM information The LCM shows 2 kinds of funcion:
 General function:
(A)
(M
)
(L)(K)(J)(I)(H)(F) (G)(E)
(D)(C)(B)
(A) EEPROM Check Sum.
(B) # of EEPROM Code Option word.
(C) EEPROM Code Option.
(D) ELAN logo or EM78P153S IRC Freq.
Display, only for EM78P153S IRC mode, ”Current
Frequency”, as write operation is accomplished.
Otherwise, display company logo “ELAN”.
Moreover
(E) OTP Check Sum.
(F) # of OTP Code Option word.
(G) OTP Code Option.
(H) OTP Read/Program solution.
Read: Display “O” , if reading is accomplished. If not,
display “X”
Program: Display “O”, if programming is
accomplished. If not, display “X”
Program: Display “O”, When burning in internal
RC mode, the internal frequency drift must be
guaranteed in ±5%. If the display of DWTR show
the “X” message, it’s means the internal
frequency is not of the guaranteed range.(Detail
description, please refer to chapter 3.)
(I) EEPROM Read/Loading solution.
Display “O”, if loading/reading is accomplished. If not,
display “X”
5

(J) Jump connection test.
Display “O”, if the connection between Jumpand IC
which will be programmed is OK. If not, display “X”.
(K) Socket connection test.
Display “O”, if the connection between socket and IC
which will be programmed is OK. If not, display
“X”.
(L) Current detector.
(M)Voltage detector.
 Programming Counter function. This function will be active
if users keep pressing the red button for five seconds. The
LCM will switch to the programming counter function page
for ten seconds as users release the red button and will
then return back to the general function page.

(1) Total programming times after Power-On and
/RESET.
(2) Successful programming times after Power-On
and /RESET.

 Busy indicator The green LED shows 4 kinds of information:
 On: under programming. Wait for LED turns off.
 Off: programming OK, reading OK, Load OK.
 Slow blinking (1.5 cycles per second): programming
failed.
 Type blinking (2.5 cycle per second): OTP not in socket.
 Quick blinking (5 cycles per second): buffer reading failed.
◆Mode slots There are 6 mode slots which are EM78P153S/P156E/ P156N/ P257/
P447S /P447N/ P451/ P451S/P458/P459 from the left to the right. Each slot has 17
sets of jumper. Users can short jumpers with a set of jumper cap for a desired mode.
 Program Bottom To press the red button to program independently.
 Texttool / Socket To line up the bottom of a programmed IC with the bottom of
the socket.
 DC power adapter To plug with a DC power supply is 18V.
 Printer port Connector To communicate with IBM PCs or compatibles with the
printer cable.
2. Hardware requirements
 IBM PC 486 or above,
6

 640K RAM,
 VGA monitor
 Printer cable no longer than 2 meters
3. Hardware Installation
 To short the desired mode slot shown in Fig. 1 with the jumper cap
 To connect the PC and the unit with a printer cable, if collaboration of PC and the unit
is required
 To insert the DC power adapter into the wall plug on the left hand side of the unit
 Note:
 To connect the printer cable before the power cable,
 DWTR executes a self diagnosis for a few seconds as the power is supplied,
 Never ever to put a programmed device on the texttool before the self
-diagnosis finishing.
4. Software Installation
Just execute the “setup.exe” file from the disk and then follow the step by step indications
to the end.
5. What is the self-diagnosis?
 To check the buffer of DWTR. The LED is off if the check succeeds, otherwise it will
quickly blink.
 To program virtually in order to sink the residual power produced by power-on. It is
the reason why users can not put a programmed device on the texttool before the
self-diagnosis finishes.

Chapter 3Introduction of the DWTR environment
1.Getting start
Procedure 1: Start DWTR
To double click the icon of ELAN WRITER on desktop, or to select desktop menu
[start]→[ELAN DWRITER] →[ELAN DWRITER].
Fig 2: DWTR initialized

Procedure 2: Open a CDS file
To choose [Open CDS file…] from [File] menu.
Step 1: Open file: The “Open” dialog box appears as being showed in Fig. 3. After
selecting a file, then press [OK] button. The source file window appears as being
shown in Fig. 4, and it consists of check sum, option, code option value and binary
data.
Step 2: Set Option: The Option dialog depicted in Fig. 5 and Fig. 6(only IRC user’s)
appears. In accordance with the application environment, designers can mix up a
suitable combination with the code option for the selected microcontroller. After
selecting options, then press [Update] button.
Step 3: Load: To keep loading source to Buffer until loading completely or press the [OK]
button depicted in Fig. 7, which is located on the up-left corner of the whole display. If
the [OK] button is pressed during dumping, the power of the hardware must be turned
off and turned on to resume the procedure of programming.
