SM59364 8-Bits Micro-controller 64KB ISP flash & 1KB RAM embedded 1.1.1 Program Code Security MOVC instruction executed from external program memory space will not be able to fetch internal codes from on chip program memory after the chip is protected on the Writer. 1.2 Data Memory The SM59364 has 1K bytes on-chip RAM, 256 bytes of it are the same as general 8052 internal memory structure while the expanded 768 bytes on-chip RAM can be accessed by external memory addressing method (by instruction MOVX.). 1.2.1 Data Memory - Lower 128 byte ($00 to $7F) Data Memory $00 to $FF is the same as 8052. The address $00 to $7F can be accessed by direct and indirect addressing modes. Address $00 to $1F is register area. Address $20 to $2F is memory bit area. Address $30 to $7F is for general memory area. Specifications subject to change without notice contact your sales representatives for the most recent information. IDMMX-0033 6 Ver B SM59364 04/2008 SyncMOS Technologies International, Inc. 1.2.2 Data Memory - Higher 128 byte ($80 to $FF) The address $80 to $FF can be accessed by indirect addressing mode . Address $80 to $FF is data area. SM59364 8-Bits Micro-controller 64KB ISP flash & 1KB RAM embedded 1.2.3 Data Memory - Expanded 768 bytes ($0000 to $02FF) From external address $0000 to $02FF is the on-chip expanded RAM area, total 768 bytes. This area can be accessed by external direct addressing mode (by instruction MOVX). If the address of instruction MOVX @DPTR is larger than $02FF then SM59364 will generate the external memory control signal automatically. The bit 1 (OME) of special function register $BF (SCONF) can enable or disable this expanded 768 byte RAM. The default setting of OME bit is 1 (enable).

When system reset by Watch Dog Timer overflow, WDR will be set to 1. ISPE: ISP function enable bit OME: 768 bytes on-chip RAM enable bit . ALEI: ALE output inhibit bit, to reduce EMI . Setting bit 0 (ALEI) of SCONF can inhibit the clock signal in Fosc/6Hz output to the ALE pin. The bit 1 (OME) of SCONF can enable or disable the on-chip expanded 768 byte RAM. The default setting of OME bit is 1 (enable). The bit 7 (WDR) of SCONF is Watch Dog Timer Reset bit. It will be set to 1 when reset signal generated by WDT overflow. User should check WDR bit whenever un-predicted reset happened. 2. In-System Programming (ISP) Function The SM59364 can generate flash control signal by internal hardware circuit. User utilize flash control register, flash address register and flash data register to perform the ISP function without removing the SM59364 from the system. The SM59364 provides internal flash control signals which can do flash program/chip erase/page erase/protect functions. User need to design and use any kind of interface which SM59364 can input data. User then utilize ISP service program to perform the flash program/chip erase/page erase/protect functions. 2.1 ISP Service Program The ISP service program is a user developed firmware program which resides in the ISP service program space. After user developed the ISP service program, user then determine the size of the ISP service program. User need to program the ISP service program in the SM59364 for the ISP purpose. The ISP service program were developed by user so that it should includes any features which relates to the flash memory programming function as well as communication protocol between SM59364 and host device which output data to the SM59364. For example, if user utilize UART interface to receive/transmit data between SM59364 and host Specifications subject to change without notice contact your sales representatives for the most recent information.

SM59364 8-Bits Micro-controller 64KB ISP flash & 1KB RAM embedded device, the ISP service program should include baud rate, checksum or parity check or any error-checking mechanism to avoid data transmission error. The ISP service program can be initiated under SM59364 active or idle mode. It can not be initiated under power down mode. 2.2 Initiate ISP Service Program To initiate the ISP service program is to load the program counter (PC) with start address of ISP service program and execute it. There are two ways to do so: (1) Blank reset. Hardware reset with first flash address blank ($0000=#FFH) will load the PC with start address of ISP service program. (2) Execute ‘JUMP’ instruction can load the start address of the ISP service program to PC. User can initiate general 8052 INT function to initiate the ISP service program. After ISP service program executed, user need to reset the SM59364, either by hardware reset or by WDT, or jump to the address $0000 to re-start the firmware program.

The flash memory address should not include the ISP service program space address. If the flash memory address indicated by ISPFAH & ISPFAL registers overlay with the ISP service program space address, the flash program/page erase of ISP function executed thereafter will have no effect.

That is: MOV ISPFD, #55H MOV ISPFD, #0AAH MOV ISPFD, #55H Any attempt to set START bit will not be allowed without the procedure above. After START bit set to 1 then the SM59364 hardware circuit will latch address and data bus and hold the program counter until the START bit reset to 0 when ISP function finished. User does not need to check START bit status by software method.

To perform byte program/page erase ISP function, user need to specify flash address at first. When performing page erase function, SM59364 will erase entire page which flash address indicated by ISPFAH & ISPFAL registers located within the page. e.g. flash address: $XYMN Specifications subject to change without notice contact your sales representatives for the most recent information.

SM59364 8-Bits Micro-controller 64KB ISP flash & 1KB RAM embedded page erase function will erase from $XY00 to $X(Y+1)FF (Y:even number), or page erase function will erase from $X(Y-1) 00 to $XYFF (Y:odd number) To perform the chip erase ISP function, SM59364 will erase all the flash program memory except the ISP service program space, also, SM59364 will un-protect the flash memory automatically. To perform chip protect ISP function, the SM59364 flash memory content will be read #00H. e.g. ISP service program to do the byte program - to program #22H to the address $1005H MOV SCONF,#04H MOV ISPFAH,#10H MOV ISPFAL,#05H MOV ISPFD,#22H MOV ISPC,#80H ; enable SM59364 ISP function ; set flash address-high, 10H ; set flash address-low, 05H ; set flash data to be programmed, data = 22H ; start to program #22H to the flash address $1005H ; after byte program finished, START bit of ISPC will be reset to 0 automatically ; program counter then point to the next instruction ISP Registers - System Control Register (SCONF,$BF) bit-7 WDR Read / Write: Reset value: R/W 0 Unused * Unused * Unused * Unused * ISPE R/W 0 OME R/W 1 bit-0 ALEI R/W 0 The bit 2 (ISPE) of SCONF is ISP enable bit. User can enable overall SM59364 ISP function by setting ISPE bit to 1, to disable overall ISP function by set ISPE to 0. The function of ISPE behaves like a security key. User can disable overall ISP function to prevent software program be erased accidentally. 3. Watch Dog Timer The Watch Dog Timer (WDT) is a 16-bit free-running counter that generate reset signal if the counter overflows. The WDT is useful for systems which are susceptible to noise, power glitches, or electronics discharge which causing software dead loop or runaway. The WDT function can help user software recover form abnormal software condition. The WDT is different from Timer0, Timer1 and Timer2 of general 8052. To prevent a WDT reset can be done by software periodically clearing the WDT counter. User should check WDR bit of SCONF register whenever un-predicted reset happened The WDT has selectable divider input for the time base source clock. To select the divider input, the setting of bit2~bit0 (PS2~PS0) of Watch Dog Timer Control Register (WDTC) should be set accordingly. To enable the WDT is done by setting 1 to the bit 7 (WDTE) of WDTC. After WDTE set to 1, the 16-bit counter starts to count with the selected time base source clock which set by PS2~PS0. It will generate a reset signal when overflows. The WDTE bit will be cleared to 0 automatically when SM59364 been reset, either hardware reset or WDT reset. To reset the WDT is done by setting 1 to the CLEAR bit of WDTC. This will clear the content of the 16-bit counter and let the counter re-start to count from the beginning.
