Description
The SM89516A series product is an 8 - bit single chip micro controller with 64KB on-chip flash and 1K byte RAM embedded. It is a derivative of the 8052 micro controller family. It has 5-channel SPWM build-in. With its hardware features and powerful instruction set, it's straight forward to make it a versatile and cost effective controller for those applications which demand up to 32 I/O pins for PDIP package or up to 36 I/O pins for PLCC/QFP package, or applications which need up to 64K byte flash memory for program data. To program the on-chip flash memory, a commercial writer is available to do it in parallel programming method.

SM89516A has 768 byte on-chip RAM which can be accessed by external memory addressing method only. (By instruction MOVX). The address space of instruction MOVX @Rn is determined by bit 1 and bit 0 (RAMS1, RAMS0) of RCON. The default setting of RAMS1, RAMS0 bits is 00 (page0). RAMS1 0 0 1 RAMS0 0 1 0 MOVX @Ri i=0,1 mapping to expended RAM address $0000 ~ $00FF $0100 ~ $01FF $0200 ~ $02FF

1.3 I/O Pin Configuration
SM89516A
8-Bits Micro-controller With 64KB flash & 1KB RAM embedded
The ports 1, 2 and 3 of standard 8051 have internal pull-up resistor, and port 0 has open-drain outputs. Each I/O pin can be used independently as an input or an output. For I/O ports to be used as an input pin, the port bit latch must contain a `1' which turns off the output driver FET. Then for port 1, 2 and 3 port pin is pulled high by a weak internal pull-up, and can be pulled low by an external source. The port 0 has open-drain outputs which means its pull-ups are not active during normal port operation. Writing `1' to the port 0 bit latch will causing bit floating so that it can be used as a high-impedance input. The port 4 used as GPIO will has the same function as port 1, 2 and 3.
2. Port 4 for PLCC or QFP package :
The bit addressable port 4 is available with PLCC or QFP package. The port 4 has only 4 pins and its port address is located at 0D8H. The function of port 4 is the same as the function of port 1, port 2 and port 3.

The bit 3, bit 2, bit 1, bit 0 output the setting to pin P4.3, P4.2, P4.1, P4.0 respectively. The port 4 output buffers can sink 20mA and can drive LED display directly.

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 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 WDR bit of SCONF register whenever un-predicted reset happened The purpose of the secure procedure is to prevent the WDTC value from being changed when system runaway. There is a 250KHz RC oscillator embedded in chip. Set WDTE = "1" will enable the RC oscillator and the frequency is independent to the system frequency. 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 RC oscillator. It will generate a reset signal when overflows. The WDTE bit will be cleared to 0 automatically when SM8958A been reset, either hardware reset or WDT reset. To reset the WDT is done by setting 1 to the CLEAR bit of WDTC before the counter overflow. This will clear the content of the 16-bit counter and let the counter re-start to count from the beginning.

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
4. Reduce EMI Function
The SM89516A 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.
5. Specific Pulse Width Modulation (SPWM)
The Specific Pulse Width Modulation (SPWM) module contain 1 kind of PWM sub module: SPWM (Specific PWM). SPWM has five 8-bit channels.
5.1 SPWM Function Description:
The 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 SPFS[1:0] settings of SPWMC ($A3) register are dividend of Fosc to be SPWM clock, Fosc/2^(SPFS[1:0]+1). The SPWM output cycle frame repetition rate (frequency) equals (SPWM clock)/32 which is [Fosc/2^(SPFS[1:0]+1)]/32.
