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 of general 8051. To prevent a WDT reset can be done by software periodically clearing the WDT counter. The SM8951B 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-bits 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 SM8951B 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-bits counter and let the counter re-start to count from the beginning.

When system reset by Watch Dog Timer overflow, WDR will be set to 1. ALEI : ALE output inhibit bit. It can 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. Reduce EMI Function The SM8951B 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/6 Hz output to the ALE pin. This function is available when there is no external program memory or no external data RAM in the system.

XI X'tal SM8951B R X2 C1 C2 Power Saving Mode The SM8951B has several features that help the user to control the power consumption of the device. The powers saving features are basically the Power Down mode, Economy mode and the Idle mode of operation.

SM8951B 8-Bits Micro-controller With4KBFlashROM&128bytesRAM embedded Idle Mode: The user can put the device into idle mode by writing 1 to the bit PCON.0. The instruction that sets the idle bit is the last instruction that will be executed before the device goes into Idle Mode. In the Idle Mode, the clock to the CPU is halted, but not to the Interrupt, Timer and Serial port blocks. This forces the CPU state to be frozen; the Program counter, the Stack Pointer, the Program Status Word, the Accumulator and the other registers hold their contents. The ALE and PSEN pins are held high during the idle state. The port pins hold the logical states they had at the time idle was activated. The idle mode can be terminated in two ways. Since the interrupt controller is still active, the activation of any enabled interrupt can wake up the processor. This will automatically clear the idle bit, terminate the idle mode, and the Interrupt Service Routine (ISR) will be executed. After the ISR, execution of the program will continue from the instruction that put the device into idle mode. The Idle mode can also be exited by activating the reset. The device can be put into reset either applying a high on the external RST pin or a Power on reset condition. The external reset pin has to be held high for at least two machine cycles to be recognized as a valid reset. In the reset condition the program counter is reset to 0000H and all the SFRs are set to the reset condition. Since the clock is already running there is no delay and execution start immediately. When the SM8951B is exiting from an idle mode with a reset, the instruction following the one that put the device into idle mode is not executed. So there is no danger of unexpected writes. Power Down Mode: The device can be put into Power Down mode by writing 1 to bit PCON.1. The instruction that does this will be the last instruction to be executed before the device goes into Power Down mode. In the Power Down mode, all the clocks are stopped and the device comes to a halt. All activity is completely stopped and the power consumption is reduced to the lowest possible value. In this state the ALE and PSEN pins are pull low. The port pins output the values held by their respective SFRs.
