1 SyncMOS Technologies International, Inc. ISP Application tes vember ISP Introduction ISP (In System Program) is a function that allows user to directly update MCU code on system board. For example, With ISP firmware code residing in MCU, user can select RS-232 or LTP1 to execute functions of erase and program for MCU. Before user uses ISP, it is essential to program an appropriate ISP firmware code to MCU with writer first (Please see te 1, te 2). On picture 1, we demonstrate the configuration setting for user uses MSM9169 writer of SyncMOS to program an appropriate ISP firmware code into MCU. User shall select N=1 if your PC runs WinHOST 3.2A. On the other hand, regardless of what commercial writer users have, if user s PC runs WinHOST 3.2A, it is essential for user to select N=1 while programming an appropriate ISP firmware code. Setting N=1 is to protect the address block FE00~FFFF (512 bytes) where the ISP firmware code resides in. Picture 1: MSM9169 writer config. Setting te 1. If you would like to implement ISP by running WinHOST 3.2A, and you use SM5964 or SM5964A or SM59264 MCU, please make sure the ISP Firmware Code, ISP AUTO 30C.bin has been successfully programmed into MCU, and Config was set N=1. te 2. If you use SM59128, the ISP Firmware Code is SM59128 ISP CODE.bin. -1-

Hardware Setup: Connect MSM9040 to Printer Port of PC. Plug socket with 5V power adapter. The output is VGA cable. b) Software Setup: Select SM59264/SM5964A/SM59128 and LTP1 in client application WinHost V3.X. At IIC SETTING, ID is 36h, Delay is 5us (SCL pulse width). Please select CHIP ERASE prior to PROGRAM. -3-

The speeds much match the ISP baud rate of MCU. Please select CHIP ERASE prior to PROGRAM c.) If you intend to download user code over 63.5 K, it is not allowed. -5-

6 SyncMOS Technologies International, Inc. ISP Application tes vember 2006 Since the size of SyncMOS ISP Firmware Code is 0.5KB, hence the allowable user s maximal code size is 63.5KB. PS. If you use SM59128, the specific ISP code must be programmed in both BANK0 and BANK1 to prevent MCU ISP not work. 3. Coding Insert subroutine in program Insert GOTOISP.A51 to project, and modify as follows: Main Program #include<.h> extern void GoToIsp(void); //User need define the function first void main(void) { if(p4.3 = = 0) //if key P4.3 equal low, it jump to ISP subroutine { GoToIsp(); } } PS. hardware and only by software methodology can enter SM5964 ISP mode GOTOISP.A NAME GOTOISP?PR?GotoIsp?GOTOISP SEGMENT CODE PUBLIC GotoIsp RSEG?PR?GotoIsp?GOTOISP -6-

16 SyncMOS Technologies International, Inc. ISP Application tes vember Troubleshooting (1.) If any fail message pop-up pleases push the ok button and reset target board. If the executing application doesn t respond any message, please check if your execution version is correct (WinHostV3.X) and reset target board. Execute it again. (2.) The possible reasons cause ISP fail: a.) Bad wiring b.) The ISP area isn t protected in MCU. When ERASE is executing, it ll clean ISP code. You need to set config. N=1, and select Protect function (Eample uses the XELTEK Writer). c.) Please don t execute ISP function immediately after system reset. d.) Please doesn t open another PC execution application or move ISP s window on XP when ISP is executing. e.) Adapter board has no power. (Check MSM9041 or MSM9040) f.) If user uses SM59128, please note: Although you have set N=1, the ISP code in bank1 will be erased if user executes ISP Chip Erase. We strongly recommend customer use the ISP PAGE Erase to prevent ISP code in Bank1 is erased. 7. Remark: (1.) If user develops ISP application by his own. Please do double Chip Erase or double Page Erase for confirming Flash data is well cleaned. (2.) User needs to execute Auto Scan Baud Rate each time when MCU reset. (3.) The Mhz and Mhz crystal can use bps and 57600bps directly without Auto Scan. (4.) Auto Scan function can be executed one time for system reset. (5.) Check COM port is correct. -16-
