Notes：
1. The pin Reset/P4.7 factory default is Reset, user must keep this pin at low during power-up. User can configure it to
GPIO (P4.7) by a flash programmer.
2. To avoid accidentally entering ISP-Mode(refer to section 16.4), care must be taken not asserting pulse signal at P3.0
during power-up while P2.6、P2.7、P4.3 are set to high.
3. To apply ICP function, OSI_SDA/P4.6 and OCI_SCL/P4.7 must be set to Bi-direction mode if they are configured as
GPIO in system.

The program can be loaded into the embedded 64KB/36KB/20KB Flash memory via writer or In-System Programming
(ISP)。
1.2.
IO Pads
The SM59R16A5 has six I/O ports: Port 0, Port 1, Port 2, Port 3, Port 4, and Port 5. Ports 0, 1, 2, 3, 4 are 8-bit ports and
Port 5 is a 6-bit port. These are: quasi-bidirectional (standard 8051 port outputs), push-pull, open drain, and input-only. As
description in section 5。
The OCI_SCL、ALE、OCI_SDA and RESET can be configured as I/O ports P4.4、P4.5、P4.6 and P4.7 by writer or in ISP
mode.
The XTAL2 and XTAL1 can be configured as I/O ports P5.4 and P5.5 by writer or in ISP mode, when the on-chip
RC-Oscillator is set to main system clock source.
All the pins on P0 ~ P5 are with slew rate adjustment to reduce EMI. The other way to reduce EMI is to disable the ALE
output if unused. This is selected by its SFR. The IO pads can withstand 4KV ESD in human body mode guaranteeing the
SM59R16A5’s quality in high electro-static environments.
1.3.
2T/1T Selection
The conventional 52-series MCUs are 12T, i.e., 12 oscillator clocks per machine cycle. SM59R16A5 is a 2T or 1T MCU,
i.e., its machine cycle is two-clock or one-clock. In the other words, it can execute one instruction within two clocks or
only one clock. The difference between 2T mode and 1T mode are given in the example in Fig. 1-1.
Fig. 1-1(a): The waveform of internal instruction signal in 2T mode
Fig. 1-1(b): The waveform of internal instruction signal in 1T mode
The default is in 2T mode, and it can be changed to 1T mode if IFCON [7] (at address 8Fh) is set to high any time. Not
every instruction can be executed with one machine cycle. The exact machine cycle number for all the instructions are
given in the next section.

Software RESET function
SM59R16A5 provides one software reset mechanism to reset whole chip. To perform a software reset, the firmware must
write three specific values 55h, AAh and 5Ah sequentially to the TAKEY register to enable the Software Reset register
(SWRES) write attribute. After SWRES register obtain the write authority, the firmware can write FFh to the SWRES
register. The hardware will decode a reset signal that “OR” with the other hardware reset. The SWRES register is
self-reset at the end of the software reset procedure.

Clocks
The default clock is the external crystal. This clock is used during the initialization stage. The major work of the
initialization stage is to determine the clock source used in normal operation.
The internal clock sources are from the on-chip RC-Oscillator with programmable frequency outputs as table 1-1，the
clock source can set by writer or ICP。

3. Memory Structure
The SM59R16A5 memory structure follows general 8052 structure. It is integrate the expanded 2KB data memory and
64KB program memory.
3.1.
Program Memory
The SM59R16A5 has 64KB on-chip flash memory which can be used as general program memory or EEPROM, 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 256 byte (N=0 to 16). When N=0 means no ISP service program space available, total 64K byte memory used
as program memory. When N=1 means address $FF00 to $FFFF reserved for ISP service program. When N=2 means
memory address $FE00 to $FFFF reserved for ISP service program…etc. Value N can be set and programmed into
SM59R16A5 by the writer or ICP. It can be used to record any data as EEPROM. The procedure of this EEPROM
application function is described in the section 19 on internal ISP.

The address 80h to FFh can be accessed by indirect addressing mode.
Address 80h to FFh is data area.
3.2.3.
Data memory - Expanded 2048 bytes ($0000 to $07FF)
From external address 0000h to 07FFh is the on-chip expanded SRAM area, total 2K Bytes. This area can be accessed
by external direct addressing mode (by instruction MOVX).
If the address of instruction MOVX @DPTR is larger then 07FFh, the SM59R16A5 will generate the external memory
control signal automatically.
The address space of instruction MOVX @Ri, i=0, 1 is determined by RCON [7:0] of special function register $86 RCON
(internal RAM control register). The default setting of RCON [7:0] is 00h (page0). One page of data RAM is 256 bytes.
When EMEN = 0, the internal 2K expanded RAM is enabled. If access memory space is more than 2K byte, the value of
RCON is sent to Port2 to access external RAM.
When EMEN = 1, the internal 2K expanded RAM is disabled. The value of RCON is invalid and high byte address is
decided by register context of Port2 register P2 [7:0].

The Dual Data Pointer accelerates the moves of data block. The standard DPTR is a 16-bit register that is used to
address external memory or peripherals. In the SM59R16A5 core the standard data pointer is called DPTR, the second
data pointer is called DPTR1. The data pointer select bit chooses the active pointer. The data pointer select bit is located
in LSB of AUX register (DPS).
The user switches between pointers by toggling the LSB of AUX register. All DPTR-related instructions use the currently
selected DPTR for any activity.

Operating registers of the MDU
The MDU is handled by seven registers, which are memory mapped as special function registers. The arithmetic unit
allows operations concurrently to and independent of the CPU’s activity. Operands and results registers are MD0 to MD5.
Control register is ARCON. Any calculation of the MDU overwrites its operands.

MDEF: Multiplication Division Error Flag.
The MDEF is an error flag. The error flag is read only. The error flag indicates an
improperly performed operation (when one of the arithmetic operations has been
restarted or interrupted by a new operation). The error flag mechanism is automatically
enabled with the first write to MD0 and disabled with the final read instruction from MD3
multiplication or shift/normalizing) or MD5 (division) in phase three.
The error flag is set when:
1. Phase two in process and write access to mdx registers (restart or interrupt
calculations)
The error flag is reset only if:
Phase two finished (arithmetic operation successful completed) and read access to MDx
registers.
MDOV: Multiplication Division Overflow flag. The overflow flag is read only.
The overflow flag is set when:
1. Division by Zero
2. Multiplication with a result greater then 0000FFFFh
3. Start of normalizing if the most significant bit of MD3 is set(MD3.7=1)
The overflow flag is reset when:
Write access to MD0 register(Start Phase one)

SLR: Shift direction bit.
SLR = 0 – shift left operation.
SLR = 1 – shift right operation.
SC[4:0]: Shift counter.
When preset with 00000b, normalizing is selected. After normalize sc.0 – sc.4 contains
the number of normalizing shifts performed. When sc.4 – sc.0 ≠ 0, shift operation is
started. The number of shifts performed is determined by the count written to sc.4 to sc.0.

Operation of the MDU
The operation of the MDU consists of three phases:
6.2.1.
First phase: loading the MDx registers, x = 0~5:
The type of calculation the MDU has to perform is selected following the order in which the mdx registers are written to.

Second phase: executing calculation.
During executing operation, the MDU works on its own parallel to the CPU. When MDU is finished, the MDUF register will
be set to one by hardware and the flag will clear at next calculation.

Here the operation of normalization and shift will be explained more. In normalization, all reading zeroes in registers
MD0 to MD3 are removed by shift left. The whole operation is completed when the MSB (most significant bit) of MD3
register contains a ’1’. After normalizing, bits ARCON.4 (MSB) to ARCON.0 (LSB) contain the number of shift left
operations. As for shift, SLR bit (ARCON.5) has to contain the shift direction, and ARCON.4 to ARCON.0 represent the
shift count (which must not be 0). During shift, zeroes come into the left or right end of the registers MD0 or MD3,
respectively.
6.3.
Normalizing
All reading zeroes of integers variables in registers MD0 to MD3 are removed by shift left operations. The whole operation
is completed when the MSB (most significant bit) of MD3 register contains a ’1’. After normalizing, bits ARCON.4 (MSB)
to ARCON.0 (LSB) contain the number of shift left operations, which were done.
6.4.
Shifting
SLR bit (ARCON.5) has to contain the shift direction, and ARCON.4 to ARCON.0 the shift count (which must not be 0).
During shift, zeroes come into the left or right end of the registers MD0 or MD3, respectively.

7. Timer 0 and Timer 1
The SM59R16A5 has three 16-bit timer/counter registers: Timer 0, Timer 1 and Timer 2. All can be configured for counter
or timer operations.
In timer mode, the Timer 0 register or Timer 1 register is incremented every 12 machine cycles, which means that it
counts up after every 12 periods of the clk signal.
In counter mode, the register is incremented when the falling edge is observed at the corresponding input pin T0or T1.
Since it takes 2 machine cycles to recognize a 1-to-0 event, the maximum input count rate is 1/2 of the oscillator
frequency. There are no restrictions on the duty cycle, however to ensure proper recognition of 0 or 1 state, an input
should be stable for at least 1 machine cycle.
Four operating modes can be selected for Timer 0 and Timer 1. Two Special Function registers (TMOD and TCON) are
used to select the appropriate mode.

Timer 2 function
Timer 2 can operate as timer, event counter, or gated timer as explained later.
8.1.1.
Timer mode
In this mode Timer 2 can by incremented in various frequency that depending on the prescaler. The prescaler is selected
by bit T2PS[2:0] in register T2CON.
8.1.2.
Event counter mode
In this mode, the timer is incremented when external signal T2 change value from 1 to 0. The T2 input is sampled in
every cycle. Timer 2 is incremented in the cycle following the one in which the transition was detected.
8.1.3.
Gated timer mode
In this mode, the internal clock which incremented timer 2 is gated by external signal T2.
8.1.4.
Reload of Timer 2
Reload (16-bit reload from the crc register) can be executed in the following two modes:
Mode 0: Reload signal is generate by a Timer 2 overflows - auto reload
Mode 1: Reload signal is generate by a negative transition at the corresponding input pin T2EX.
8.2.
Compare function
In the four independent comparators, the value stored in any compare/capture register is compared with the contents of
the timer register. The compare modes 0 and 1 are selected by bits C0CAMx. In both compare modes, the results of
comparison arrives at Port 1 within the same machine cycle in which the internal compare signal is activated.
When the channel 1、2 and 3 use at compare function，The compare mode setting of Channel 2 and Channel 3 should be

same as the compare mode setting of channel 1.
8.2.1.
Compare Mode 0
In mode 0, when the value in Timer 2 equals the value of the compare register, the output signal changes from low to high.
It goes back to a low level on timer overflow. In this mode, writing to the port will have no effect, because the input line
from the internal bus and the write-to-latch line are disconnected. The following figure illustrates the function of compare
mode 0.

Compare Mode 1
In compare mode 1, the transition of the output signal can be determined by software. A timer 2 overflow causes no
output change. In this mode, both transitions of a signal can be controlled. Fig. 8-2 shows a functional diagram of a
register/port configuration in compare Mode 1. In compare Mode 1, the value is written first to the “Shadow Register”,
when compare signal is active, this value is transferred to the output register.

Capture Mode 0
In mode 0, value capture of Timer 2 is executed when:
(a) Rising edge on input CC0-CC3
(b) Falling edge on input CC0-CC3
(c) Both rising and falling edge on input CC0-CC3
The contents of Timer 2 will be latched into the appropriate capture register.

Capture Mode 1
In mode 1, value capture of timer 2 is caused by writing any value into the low-order byte of the dedicated capture register.
The value written to the capture register is irrelevant to this function. The contents of Timer 2 will be latched into the
appropriate capture register.

9. Serial interface 0 and 1
There are two serial interfaces for data communication in SM59R16A5, they are the so called UART0 and UART1.
As the conventional UART, the communication speed can be selected by configuring the baud rate in SFRs.
These two serial buffers consists of two separate registers, a transmit buffer and a receive buffer. Writing data to the
SFR S0BUF or S1BUF sets this data in serial output buffer and starts the transmission. Reading from the S0BUF or
S1BUF reads data from the serial receive buffer. The serial port can simultaneously transmit and receive data. It can
also buffer 1 byte at receive, which prevents the receive data from being lost if the CPU reads the second byte before the
transmission of the first byte is completed.

Mode 2
This mode is similar to Mode 1, but with two differences. The baud rate is fixed at 1/32 (SMOD=1) or 1/64(SMOD=0) of
oscillator frequency, and 11 bits are transmitted or received: a start bit (0), 8 data bits (LSB first), a programmable Bit 9,
and a stop bit (1). Bit 9 can be used to control the parity of the serial interface: at transmission, bit TB80 in S0CON is
output as Bit 9, and at receive, Bit 9 affects RB80 in SFR S0CON.

multiprocessor communication. In this case, the slave processors have bit SM20 in S0CON or SM21 in S1CON set to 1.
When the master processor outputs slave’s address, it sets the Bit 9 to 1, causing a serial port receive interrupt in all the
slaves. The slave processors compare the received byte with their network address. If matched, the addressed slave
will clear SM20 or SM21 and receive the rest of the message, while other slaves will leave SM20 or SM21 bit unaffected
and ignore this message. After addressing the slave, the host will output the rest of the message with the Bit 9 set to 0, so
no serial port receive interrupt will be generated in unselected slaves.

10. Watchdog timer
The Watch Dog Timer (WDT) is an 8-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 from 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 WDTF bit of WDTC register whenever un-predicted reset happened. After
an external reset the watchdog timer is disabled and all registers are set to zeros.
The watchdog timer has a free running on-chip RC oscillator (250KHz ±20%). The WDT will keep on running even after
the system clock has been turned off (for example, in sleep mode). During normal operation or sleep mode, a WDT
time-out (if enabled) will cause the MCU to reset. The WDT can be enabled or disabled any time during the normal mode.
Please refer the WDTE bit of WDTC register. The default WDT time-out period is approximately 16.38ms (WDTM [3:0] =
0100b).
The WDT has selectable divider input for the time base source clock. To select the divider input, the setting of bit3 ~ bit0
(WDTM [3:0]) of Watch Dog Timer Control Register (WDTC) should be set accordingly.

When MCU is reset, the MCU will be read WDTEN control bit status. When WDTEN bit is set to 1, the watchdog function
will be disabled no matter what the WDTE bit status is. When WDTEN bit is clear to 0, the watchdog function will be
enabled if WDTE bit is set to 1 by program. User can to set WDTEN on the writer or ISP.
The program can enable the WDT function by programming 1 to the WDTE bit premise that WDTEN control bit is clear to
0. After WDTE set to 1, the 8 bit-counter starts to count with the selected time base source clock which set by WDTM [3:0].
It will generate a reset signal when overflows. The WDTE bit will be cleared to 0 automatically when MCU been reset,
either hardware reset or WDT reset.
Once the watchdog is started it cannot be stopped. User can refreshed the watchdog timer to zero by writing 0x55 to
Watch Dog Timer refresh Key (WDTK) register. This will clear the content of the 8-bit counter and let the counter re-start

11. Interrupt
The SM59R16A5 provides 15 interrupt sources with four priority levels. Each source has its own request flag(s) located in
a special function register. Each interrupt requested by the corresponding flag could individually be enabled or disabled
by the enable bits in SFR’s IEN0, IEN1, and IEN2.
When the interrupt occurs, the engine will vector to the predetermined address as shown in Table 11.1. Once interrupt
service has begun, it can be interrupted only by a higher priority interrupt. The interrupt service is terminated by a return
from instruction RETI. When an RETI is performed, the processor will return to the instruction that would have been next
when interrupt occurred.
When the interrupt condition occurs, the processor will also indicate this by setting a flag bit. This bit is set regardless of
whether the interrupt is enabled or disabled. Each interrupt flag is sampled once per machine cycle, and then samples are
polled by hardware. If the sample indicates a pending interrupt when the interrupt is enabled, then interrupt request flag is
set. On the next instruction cycle the interrupt will be acknowledged by hardware forcing an LCALL to appropriate vector
address.
Interrupt response will require a varying amount of time depending on the state of microcontroller when the interrupt
occurs. If microcontroller is performing an interrupt service with equal or greater priority, the new interrupt will not be
invoked. In other cases, the response time depends on current instruction. The fastest possible response to an interrupt is
7 machine cycles. This includes one machine cycle for detecting the interrupt and six cycles for perform the LCALL.

12.1. Idle mode
Setting the IDLE bit of PCON register invokes the IDLE mode. The IDLE mode leaves internal clocks and peripherals
running. Power consumption drops because the CPU is not active. The CPU can exit the IDLE state with any interrupts or
a reset.

Setting the STOP bit of PCON register invokes the STOP mode. All internal clocking in this mode is turn off. The CPU will
exit this state only if interrupts asserted from external INT0/1, KBI, LVI, and RTC, or a hardware reset by WDT and LVR.

14. IIC function
The IIC module uses the SCL (clock) and the SDA (data) line to communicate with external IIC interface. Its speed can be
selected to 400Kbps (maximum) by software setting the IICBR [2:0] control bit. The IIC module provided 2 interrupts
(RXIF, TXIF). It will generate START, repeated START and STOP signals automatically in master mode and can detects
START, repeated START and STOP signals in slave mode. The maximum communication length and the number of
devices that can be connected are limited by a maximum bus capacitance of 400pF.
The interrupt vector is 6Bh.

15. SPI function
Serial Peripheral Interface (SPI) is a synchronous protocol that allows a master device to initiate communication with
slave devices.
The interrupt vector is 4Bh.
There are 4 signals used in SPI, they are
SPI_MOSI: data output in the master mode, data input in the slave mode,
SPI_MISO: data input in the master mode, data output in the slave mode,
SPI_SCK: clock output form the master, the above data are synchronous to this signal
SPI_SS: input in the slave mode.
This slave device detects this signal to judge if it is selected by the master.
In the master mode, it can select the desired slave device by any IO with value = 0.

slave device via the MOSI line, the slave device responds sends data back to the master device
via the MISO line. This implies that full-duplex transmission with both out-data and in-data are

19. In-System Programming (Internal ISP)
The SM59R16A5 can generate flash control signal by internal hardware circuit. Users utilize flash control register, flash
address register and flash data register to perform the ISP function without removing the SM59R16A5 from the system.
The SM59R16A5 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 SM59R16A5 can input data. User then utilize ISP
service program to perform the flash program/chip erase/page erase/protect functions.
19.1. 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 SM59R16A5 for the ISP purpose.
The ISP service programs 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 SM59R16A5 and host device which
output data to the SM59R16A5. For example, if user utilize UART interface to receive/transmit data between
SM59R16A5 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 SM59R16A5 active or idle mode. It can not be initiated under power
down mode.
19.2. 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 $F000 to $FFFF. It can be divided as blocks of N*256 byte. (N=0 to
16). 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 256 byte while the rest of 63.75K byte flash memory can be used as program
memory. The maximum ISP service program allowed is 4K byte when N=16. Under such configuration, the usable
program memory space is 60K byte.
After N determined, SM59R16A5 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. As shown in Table 19-1.
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 has been protected, the content of ISP
service program still can be read. If the flash has been protected, the overall content of flash program memory space
including ISP service program space can not be read.

19.3. 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
needs to erase the locked ISP service program, he can do it by writer only. User can not change ISP service program
when SM59R16A5 was in system.
19.4. 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 four 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. The hardware reset includes Internal (power on reset) and external
pad reset.
(2) Execute jump instruction can load the start address of the ISP service program to PC.
(3) Enters ISP service program by hardware setting. User can force SM59R16A5 enter ISP service
program by setting P2.6, P2.7 “active low” or P4.3 “ active low” during hardware reset period. The
hardware reset includes Internal (power on reset) and external pad reset. In application system
design, user should take care of the setting of P2.6, P2.7 or P4.3 at reset period to prevent
SM59R16A5 from entering ISP service program.
(4) Enter’s ISP service program by hardware setting, the port3.0 will be detected the two clock signals
during hardware reset period. The hardware reset includes Internal (power on reset) and external
pad reset. And detect 2 clock signals after hardware reset.
During hardware reset period, the hardware will detect the status of P2.6/P2.7/P4.3/P3.0. If they meet one of above
conditions, chip will switch to ISP mode automatically. After ISP service program executed, user need to reset the
SM59R16A5, either by hardware reset or by WDT, or jump to the address $0000 to re-start the firmware program.
There are 8 kinds of entry mechanisms for user different applications. This entry method will select on the writer or
ISP.

ISP enable bit (ISPE) is read-only by default, software must write three specific values 55h, AAh and 5Ah
sequentially to the TAKEY register to enable the ISPE bit write attribute. That is:
MOV TAKEY, #55h

The bit 0 (ISPE) of IFCON is ISP enable bit. User can enable overall SM59R16A5 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. ISP registers ISPFAH,
ISPFAL, ISPFD and ISPFC are read-only by default. Software must be set ISPE bit to 1 to enable these 4

The choice ISP function will start to execute once the software write data to ISPFC register.
To perform byte program/page erases ISP function, user need to specify flash address at first. When
performing page erase function, SM59R16A5 will erase entire page which flash address indicated by ISPFAH

e.g. flash address: $XYMN
page erase function will erase from $XY00 to $XYFF
To perform the chip erase ISP function, SM59R16A5 will erase all the flash program memory except the ISP
service program space. To perform chip protect ISP function, the SM59R16A5 flash memory content will be
read #00H.

21. OPA/Comparator
SM59R16A5 had integrated an OPA/Comparator module on chip. This module supports OPA and Comparator
modes individually according to user’s configuration. When OPA Mode enabled, dual OP-Amps may be applied to
single or two-stage amplifier network, and may be applied as a front-end signal process and internally routed to
specific ADC channel. When Comparator Mode enabled, an internal reference voltage is available to be configured
on comparator terminals.
If OPA and Comparator Mode both are enabled at same module, the OPA Mode has higher priority.
The OPA/Comparator SFR show as below:
