Watchdog Timer Watchdog timer adopts independent counter. Watchdog (WDT) is mainly used for program monitor. After counting overflows, it generates reset signal to avoid endless loop or other error execution status. The longest overflow time is 873.6ms with 75KHz crystal oscillator. Operating mode control SC9307P work in three modes: normal mode, sleep mode, and data hold mode. Normal mode can be divided into high-speed mode and low-speed mode. The difference is the different system clock sources. The high speed mode system clock comes from internal RC oscillator or high speed oscillator extended by PC4/5, while the low speed mode system clock comes from external low speed oscillator. After power on, CPU clock is provided by internal RC oscillator which needs to turn on internal reference module. Select clock frequency or switch to the external low speed clock (75KHz) by setting system control register and clock control register. The MCU enters sleep mode by setting SLEEP flag of MCU sleep control register MCU_SLP as 1. After the MCU enters sleep mode, external 75KHz oscillator still works, and CPU clock will be turned off. But it can still response to internal timer interrupt or external IO interrupt. The circuit enters sleep mode which can reduce the

system standby power dissipation (with 75KHz crystal oscillator, when RTC enables at 3V operating voltage, typical power dissipation current is less than 5A). Reset, internal or external interrupt can wake up CPU and make it enter work in full speed. When system clock comes from external low speed oscillator, if this oscillator is closed by program, the circuit will enter data hold mode. In this mode, RAM data is saved. The dissipation current is reduced to less than 1uA. External IO interrupt or reset can make the oscillator work again. Note: The clock should be switch to 75KHz before entering the sleep mode. Turn off the power reference circuit and other relative circuits to reduce the power dissipation. Clock and Reset SC9307P supports many selectable operating clocks. The clock source can be external 75KHz crystal oscillator, and can also be the clock generated by internal RC oscillator. When high precision and high speed is needed, it can extend high frequency external oscillator through PC4/5. The structure is as follows:
The system reset occurs when: internal watchdog counting overflows; external Reset pin input low level. The circuit jumps to the start address of the program from reset address FFFAH and begins working normally.
www..comhas built in RC oscillator, and frequency of RC oscillator is about 3.2MHz when supply voltage is 3V. SC9307P
If only fast response to internal and external events is needed without high precision, RC oscillator can be adopted as CPU clock to make the system process the events quickly. RC oscillator will vary following the voltage and temperature, so PC4/PC5 must be used to extend high-speed oscillator to satisfy the system requirements under the conditions that need high-precision timing or asynchronous communication, etc.. RC oscillator begins to work after reset, and used as CPU clock. Real time Clock (RTC) RTC module can provide powerful timing function. When it starts, it will work separately from CPU. It can provide minute, hour and year/month/day, etc. in BCD formats. Minute, hour, week, day alarm can be set, and the alarm function can be triggered by interrupt or inquiring the alarm flag by software. At the same time, it will generate 0.5s real time clock signal, which can trigger interrupt. This interrupt shares one channel with alarm interrupt. It is used together with INTCON register. At the same time, it provides 4 BUZ signals to driver the buzzer. Timer T0/T1/T2 SC9307P includes three 8-bit timers Timer0, Timer1 and Timer2. Where, T0 and T1 timers can be used together as a 16-bit timer. When T0 or T1 are used separately, their functions are as follows:

T0/T1/T2 has one control register and one pre-assignment register. UART SC9307P has built-in full duplex async communication interface with three modes: 8bit variable baud rate, 9bit fixed baud rate or variable baud rate communication. O O O Pin Tx diplex with PB4, pin RX diplex with PB5 Baud rate presetting register can adjust baud rate freely Transmitting and receiving interrupt cooperation dual buffer can guarantee the high speed communication stable and reduce the CPU load. 8-bit ADC 8-bit AD converter is mainly used for keyboard scan and electronic volume display. It has 4 input channels (PC0/1/4/5). Select a channel and input switch level by program and the result is stored in an 8-bit register. Conversion clock has 4 selectable clock sources. Input internal reference voltage through channel 6 of ADC to detect the battery voltage (together with internal standard voltage). PC4/5 can also be used to extend high frequency oscillator pin, if it is not connected to oscillator, ADC input channel is not effected. One AD conversion needs 12 clock cycles, and the typical conversion time of ADC is 160s with 75KHz oscillator. Frequency counting module This module mainly includes local oscillator signal amplifier and gate control counting. FM or AM local oscillator signal is counted by a 16-bit counter after amplified. This counter gate control time can be selected as 1/4/8ms, so the local oscillator frequency can be got easily according to the counter value and gate time. I/O Port SC9307P www..comhas 5 groups of I/O ports: PA, PB, PC, PE, PF. PA has 8 pins, where 4 pins are used for external interrupt input. PB has 5 pins, where 3 pins are used for key input interrupt. PC has 5 pins, where 4 pins are shared with ADC input channel. PC.6 is used for ADC external reference voltage input. PE/PF are general I/O, 16 pins in total. So there are max. 34 pins can be used as IO pins. There are three registers for ports PA/B. Data register PORTx latches the output data, direction register TRISx controls the dataflow direction (set 1 to be output). PUA register and TRISA register can implement input pull-up or output open-drain of port A. PB has only 5 pins, port PC of PUB register is controlled by 3 registers, TRISC realizes direction selection, PORTC stores output data, APCON realizes the switch of analog channel and digital channel. Register PORTx is readable/writable. When PORTx is set as output, read the last writing data of this register; when it is set as input, read the pin state. Usage of port PE/F is different from PA/B/C. Just take port PE as an example, lower 4-bit of register PECFGL is used for controlling PE.3~0 ports. When PECFGL.3 is set as 1, PE.3 acts as output and when PECFGL.3 is set as 0, PE.3 acts as input. Lower 4-bit of register PECFGH is used for controlling PE.7~4 ports. When PECFGH.3 is set as 1, PE.7 acts as output and when PECFGH.3 is set as 0, PE.7 acts as input. Usage and function of PF are same as PE, used as output after reset. Control mode of PFCFGL, PFCFGH are same as PECFGL, PECFGH.
