1 INTRODUCTION
SONiX 8-bit micro-controller development system includes two major parts. One is In-circuit emulator
named SN8ICE 2K and the other is the integrated development environment, M2IDE. SN8ICE 2K provides
powerful and reliable emulation environment. SN8ICE2K is a totally new generation of SONiX development
tool. It supports all the SN8P2xxx series MCU. Because the new architecture, new digital function can add
and emulate at the time real chip is still under development. Also, SN8ICE 2K is no necessary to set any
jumper or switch for code option changes. The M2IDE is window based integrated development
environment including editor, assembler, debugger and writer driver. Using these two powerful tools will
save the time of any project.

In this Chapter, you will learn how to emulate the program using SN8ICE 2K.
4.1 START M2IDE
The first time start M2IDE, a welcome dialog window shows and the SN8Readme file opened. Checked
the checkbox in the welcome window will close the SN8Readme file when launch the M2IDE in next
time. SN8Readme file describe the difference from the previous version of IDE.

The main file displays at the edit window. Project file tree listed at the left of the edit window.
Figure 4-5 Edit window
4.2 DEBUG A PROJECT
Finish editing the code, start the assembler by pressing the “F7” function key, or select from the
“Debug-> build” menu. A code option window shows to select the correct code option configuration.
Code option is a hard-coding option to choose which part of circuit is used. The detail code option
description is written in each MCU’s datasheet.
Figure 4-6 Code option table example

SONiX TECHNOLOGY CO., LTD Page 13 Preliminary V0.1
The complier message shows at the Build window, including the warning messages, error messages,
resource status. Program status, like the ROM, RAM usage, is also reported at this stage.
Figure 4-7 Complier message
The program halts at the reset vector if it’s first time to run. A yellow arrow indicates where the
program counter (PC) is. An “ICE” keyword in the status bar indicates that IDE is in the debug mode.
Figure 4-8 Debug window

SONiX TECHNOLOGY CO., LTD Page 14 Preliminary V0.1
Click “Debug -> Step Over” (F10) from the menu, you could trace Macro or Subroutine of the program
in one step. When finished “Step Over” function, the yellow arrow goes to the next program flow and
stops. In this case, the program jumps to the “Reset” label. The PCL’s value is in red because the
“JMP” instruction changes the PCL value.
Figure 4-9 Step
To set a breakpoint, simply move the cursor to the line where you wish the program to be stopped. Then,
click “Debug-> Break” (F9) from the menu. The red dot represents successful breakpoint setting.

Click “Debug-> Reset” from the menu or press “Ctrl+F5” to reset the program. Then, you may emulate
again starting from the program reset vector.
4.3 CONNECT TO TARGET BY TRANSITION BOARD
The CON1 is the generic I/O port including all I/O of SN8P2xxx series. Connect different transition
board to CON1 to meet each MCU’s pin assignment. After ICE board V1.3, the CON1 is male socket.
Please populate 60 pins female socket on transition board and connect transition board to SN8ICE 2K as
following figure:
Figure 4-14 The 60 pins socket of transition board is female type

5 TROUBLE SHOOTING
Q The ICE is reset spontaneously sometimes in ICE mode.
A It occurs when the user maps his network printer to the LPT1 that is connected to the ICE system.
To solve it, just map the network printer to LPT2.
Q ICE can’t work under Windows 2000.
A When ICE works under Windows 2000/ Windows XP, LPT port should be set in the BIOS. Please
check the BIOS about the LPT configuration. It must be EPP, ECP, or Bi-direction.
Q Could ICE work emulate the 3.3 voltage supply?
A Yes. Just remove the “INTERNAL 5V” jumper (near the RESET button) and supply the 3.3V DC
power to the VDD and VSS pin of CON1 (I/O port interface) by target board.

6 APPENDIX A
6.1 SN8ICE LIMITATION
 Does not support SN8P1X series chip emulation.
 Maximum guarantee MIPS:
 8 MIPS at 5V (e.g. 16 MHz crystal and Fcpu = High_Clk / 2)
 6 MIPS at 3V
 P5.2 open drain function shift to P5.0
Solution: Add open-drain transistor in P5.2 and add pull-up resistor in P5.0
 Can’t emulate the ADCKS2 bit for SN8P270XA series chip.
Solution: Always set ADCKS = “0” in SN8ICE 2K emulation.
 12-bit ADC missing code is about 8LSB (9-bit resolution in half AVREFH input voltage, 12-bit
resolution in other input voltage)
