When system reset by Watch Dog Timer overflow, WDR will be set to 1 OME: 768 bytes on-chip RAM enable bit ALEI: ALE output inhibit bit, to reduce EMI 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. 1.3 I/O Pin Configuration 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.

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.

Extension Function Description 3.Watch Dog Timer SM89516 8-Bits Micro-controller With 64KB flash & 1KB RAM embedded 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. The SM89516 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. The WDT is enable 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 SM89516 been reset, either hardware reset or WDT reset. To reset the WDT is done by setting 1 to the bit 5 (CLEAR) of WDTC. This will clear the content of the 16-bit counter and let the counter re-start to count from the beginning. 3.1 Watch Dog Timer Registers: WDT Control Register (WDTC, $9F) bit-7 WDTE Read / Write: Reset value: R/W 0 R * Clear R/W 0 Unused * Unused * PS2 R/W 0 PS1 R/W 0 bit-0 PS0 R/W 0 WDTE : Watch Dog Timer enable bit CLEAR : Watch Dog Timer reset bit PS2~PS0 : clock source divider selection bit PS [2:0] 000 001 010 011 100 101 110 111 Divider (OSC in) 8 16 32 64 128 256 512 1024 Time Period (ms) @40MHz 13.1 26.21 52.42 104.8 209.71 419.43 838.86 1677.72 4. Reduce EMI Function The SM89516 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. This function is available when there is no external program memory or no external data RAM in the system.
