It's memory structure follows general 8052 structure . 1.1 Program Memory The SM5964 has 64K byte on-chip flash memory which used as general program memory, on which include up to 4K byte specific ISP service program memory space. The address range for the 64K byte is $0000 to $FFFF. The address range for the ISP service program is $F000 to $FFFF. The ISP service program size can be partitioned as N blocks of 512 byte (N=0 to 8). When N=0 means no ISP service program space available, total 64K byte memory used as program memory. When N=1 means memory address $FE00 to $FFFF reserved for ISP service program. When N=2 means memory address $FC00 to FFFF reserved for ISP service program,...etc. Value N can be set and programmed into SM5964 by writer. 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. .

In-System Programming (ISP) Function SM5964 8-Bits Micro-controller 64KB ISP flash & 1KB RAM embedded The SM5964 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 SM5964 from the system. The SM5964 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 SM5964 can input data. User then utilize ISP service program to perform the flash program/chip erase/page erase/protect functions. 3.1 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 SM5964 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 SM5964 and host device which output data to the SM5964. For example, if user utilize UART interface to receive/transmit data between SM5964 and host 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 SM5964 active or idle mode. It can not be initiated under power down mode. 3.2 Lock Bit (N) The Lock Bit N has two functions: one is for service program size configuration and the other is to lock the ISP service program space from flash erase function. The ISP service program space address range from $F000 to $FFFF. It can be divided as blocks of N*512 byte. (N=0 to 8). When N=0 means no ISP function, all of 64K byte flash memory can be used as program memory. When N=1 means ISP service program occupies 512 byte while the rest of 63.5K byte flash memory can be used as program memory. The maximum ISP service program allowed is 4K byte for N=8. Under such configuration, the usable program memory space is 60K byte. After N determined, SM5964 will reserve the ISP service program space downward from the top of the program address $FFFF. The start address of the ISP service program located at $Fx00 while x is an even number, depending on the lock bit N. Please see page 7 program memory diagram for this ISP service program space structure. Specifications subject to change without notice contact your sales representatives for the most recent information. Ver 2.2 SM5964 08/2006 9 SyncMOS Technologies International, Inc. SM5964 8-Bits Micro-controller 64KB ISP flash & 1KB RAM embedded The lock bit N function is different from the flash protect function. The flash erase function can erase all of the flash memory except for the locked ISP service program space. If the flash not been protected, the content of ISP service program still can be read. If the flash been protected, the overall content of flash program memory space including ISP service program space can not be read. 3.3 Program the ISP Service Program After Lock Bit N is set and ISP service program been programmed, the ISP service program memory will be protected (locked) automatically. The lock bit N has its own program/erase timing. It is different from the flash memory program/erase timing so the locked ISP service program can not be erased by flash erase function. If user need to erase the locked ISP service program, he can do it by writer only. User can not change ISP service program when SM5964 was in system. 3.4 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 three 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 SM5964, 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 SM5964 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.

Specifications subject to change without notice contact your sales representatives for the most recent information. Ver 2.2 SM5964 08/2006 11 SyncMOS Technologies International, Inc. SM5964 8-Bits Micro-controller 64KB ISP flash & 1KB RAM embedded To perform byte program/page erase ISP function, user need to specify flash address at first. When performing page erase function, SM5964 will erase entire page which flash address indicated by ISPFAH & ISPFAL registers located within the page. e.g. flash address: $XYMN 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, SM5964 will erase all the flash program memory except the ISP service program space, also, SM5964 will un-protect the flash memory automatically. To perform chip protect ISP function, the SM5964 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 SM5964 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 SM5964 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. 4. 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 SM5964 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.

SM5964 8-Bits Micro-controller 64KB ISP flash & 1KB RAM embedded 5. Reduce EMI Function The SM5964 allows user to reduce the EMI emission by setting 1 to the bit 0 (ALEI) of SCONF register. This function will inhibit the clock signal in Fosc/6Hz output to the ALE pin. 6. Specific Pulse Width Modulation (SPWM) The Specific Pulse Width Modulation (SPWM) module has five 8-bit channels, each channel contains a 8-bit wide SPWM data register (SPWMD) to decide number of continuous pulses within a SPWM frame cycle. 6.1 SPWM Function Description: Each 8-bit SPWM channel is composed of an 8-bit register which contains a 5-bit SPWM in MSB portion and a 3-bit binary rate multiplier (BRM) in LSB portion. The value programmed in the 5-bit SPWM portion will determine the pulse length of the output. The 3-bit BRM portion will generate and insert certain narrow pulses among an 8-SPWM-cycle frame. The number of pulses generated is equal to the number programmed in the 3-bit BRM portion. The usage of the BRM is to generate equivalent 8-bit resolution SPWM type DAC with reasonably high repetition rate through 5-bit SPWM clock speed. The PDIV[1:0] settings of SPWMC ($A3) register are dividend of Fosc to be SPWM clock, Fosc/2^(PDIV[1:0]+1). The SPWM output cycle frame repetition rate (frequency) equals (SPWM clock)/32 which is [Fosc/2^(PDIV[1:0]+1)]/32. 6.2 SPWM Registers - P1CON, SPWMC, SPWMR[4:0] SPWM Registers - Port1 Configuration Register (P1CON, $9B) bit-7 SPWM4E Read / Write: Reset value: R/W 0 bit-0 Unused * SPWM3E R/W 0 SPWM2E R/W 0 SPWM1E R/W 0 SPWM0E R/W 0 Unused * Unused * SPWM[4:0]E :When the bit set to one, the corresponding SPWM pin is active as SPWM function.
