Electrification reset circuit provided in this embodiment, the working principle of control circuit and the second logic circuit are as follows:
Electrification reset circuit, when just powering on, the delay generated using capacitor charging allows output end to generate a several microseconds
High level signal is used to carry out electrification reset to circuit.
Control circuit, the external control button connected to the control circuit are high electricity when not operating to it because there is pull-up resistor
Flat, when external control button is pressed, the signal in external control button becomes low level, the signal of external control button output
The high level signal of generation makes the signal that makes can control in control circuit get higher level, and entire circuit is started to work.In this implementation
In example, in order to avoid circuit is opened in false triggering, stabilization processing has been done, after needing external control button to press, has at least needed to maintain to touching
It sends out clock signal H2 in the end CK of device ZDR and the 1st rising edge occurs, so that the end Q of trigger ZDR can export a high level letter
Number, and then the end Q of subsequent ZTR device is made to generate high level, making in control circuit, which can control signal, also becomes high level, most
The signal that makes can control at the end EN is set to maintain high level always eventually, entire circuit can continue working；Even if external control button TG pine
After opening, the signal of external control button output becomes low level, because the end the Q output signal of ZTR device has been high level, remains to
So that the signal that makes can control in control circuit is maintained high level, then the end EN is maintained to make to can control signal high level.If
The time that external control button TG is pressed is too short, does not wait until that rising edge signal, the letter of external control button output occurs in H2 signal
Number become low level, the low level when end Q of ZTR device or holding circuit are closed causes to make can control in control circuit
Signal becomes low level, and the end EN, which makes to can control signal, can also immediately become low level, and circuit stops working.END is audio signal
The high level short pulse signal that middle note exports after finishing, remaining time are low level, this high level pulse signal
It is generated in address module, can make can control one same-action of signal with control circuit, generation makes to can control signal, controls
The on and off of entire circuit.
Second logic circuit, high level signal of the EN signal after phase inverter with electrification reset circuit output are patrolled second
It is done in volume circuit or operation, generates reset signal, frequency division module, address module, acceleration module, audio output module are answered
Position.When just powering on, played reset role by high level signal；When circuit does not work, EN is low level, and the reverse signal of EN is
High level plays reset role.
