Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
One embodiment of the invention discloses a circuit module which can be applied to electronic equipment such as a mobile phone, a tablet personal computer, a palm computer and the like; the electronic device includes a first circuit module and a second circuit module.
As shown in fig. 1, the circuit module may include: an integrated control unit 100 and a control module 200; wherein:
the integrated control unit 100 is provided with a reset pin 101 and a first pin 102;
the reset pin 101 is used to connect to the first circuit module 300, and the first pin 102 is used to connect to the second circuit module 400.
The control module 200 is disposed between the reset pin 101 and the first pin 102; the control module can be used to cause the current state of the reset pin to change when the current state of the first pin changes.
The change of the current state of the first pin can affect the circuit module to a certain extent, for example, a part or all of functions of the circuit module cannot be used. It should be noted that the circuit module generally has a plurality of pins, and the change of the current state of different pins can affect the same or different functions of the circuit module, so the present invention does not limit the first pin of the circuit module as long as the change of the current state can affect part or all of the functions of the circuit module.
As one implementation, the change in the current state of the first pin is used to affect a first function of the circuit module. That is, when the current state of the first pin is maintained, the circuit module has the first function, and when the current state of the first pin is changed, the first function of the circuit module cannot be used.
The specific fact that the reset pin has a state corresponding to the current state of the first pin means that when the current state of the first pin changes, the control module can enable the current state of the reset pin to also change.
It should be noted that the state of the reset pin corresponding to the current state of the first pin may indicate that the current state of the reset pin and the current state of the first pin are in the same state, or may also indicate that the current state of the first pin is in one state and the current state of the reset pin is in another state.
Correspondingly, the current state of the first pin changes, and the current state of the reset pin also changes, which may mean that the current state of the reset pin and the current state of the first pin both change in the same way, or only that the current state of the reset pin and the current state of the first pin change in different ways. As long as it is ensured that the current state of the reset pin changes when the current state of the first pin changes.
The integrated control unit 100 is capable of being reset upon detecting an excessive change in the current state of the reset pin 101.
It should be noted that the fact that the current state of the reset pin has changed means that the state of the reset pin after the change is the same as the state before the change.
After the integrated control unit is reset, all functions of the circuit module can be recovered, including the function that the change of the current state of the first pin affects the circuit module, so that the circuit module can work normally.
In the invention, the circuit module comprises an integrated control unit provided with a reset pin and a first pin and a control module arranged between the reset pin and the first pin, and the control module can change the current state of the reset pin when the current state of the first pin changes, so that a user does not need to manually check the state of the first pin to determine whether the circuit module has a fault; and because the integrated control unit can reset when detecting that the current state of the reset pin is changed, the invention can automatically control the circuit module to reset, has higher intelligence and improves the user experience.
The specific implementation mode is that the control module can enable the current state of the reset pin to be changed when the current state of the first pin is changed; in this embodiment, the control module may be specifically configured to change the current state of the reset pin from the third state to the fourth state and then to return to the third state when the current state of the first pin is changed from the first state to the second state and then to return to the first state.
Specifically, the first pin is in a first state when the current state is not changed, and the reset pin is in a third state when the current state is not changed; when the first pin is changed from the first state to the second state, the control module can also change the reset pin from the third state to the fourth state; the control module may also enable the reset pin to be restored from the fourth state to the third state when the first pin is restored from the second state to the first state.
Wherein the first state is different from the second state, and the third state is different from the fourth state.
It should be noted that the first state of the first pin and the third state of the reset pin may be the same state, and the second state of the first pin and the fourth state of the reset pin may also be the same state. For example, the first state of the first pin and the third state of the reset pin are both high level, and the second state and the fourth state are both low level; then, when the first pin changes from high level to low level and then returns to high level, the control module may change the reset pin from high level to low level and then return to high level.
Of course, the first state of the first pin and the third state of the reset pin may be different states, and the second state of the first pin and the fourth state of the reset pin may also be different states. For example, the first state of the first pin is a high level, the third state of the reset pin is a low level, the second state is a first level, and the fourth state is a high level, so that when the first pin changes from the high level to the low level and then returns to the high level, the control module may change the reset pin from the low level to the high level and then returns to the low level.
In the invention, if the time when the current state of the first pin is changed is the first time, the control module can change the current state of the reset pin at a second time after the first time. As a preferable mode, the control module may be configured to make the time when the current state of the reset pin changes and the time when the current state of the first pin changes be the same time.
In the invention, the specific implementation forms of the control module are various, and as a specific implementation form, the control module can be a diode; based on this, another embodiment of the present invention further discloses a circuit module, as shown in fig. 2, the circuit module may include: an integrated control unit 100 and a diode 201; wherein the content of the first and second substances,
the integrated control unit 100 is provided with a reset pin 101 and a first pin 102;
the reset pin 101 is used to connect to the first circuit module 300, and the first pin 102 is used to connect to the second circuit module 400.
A diode 201 is arranged between the reset pin 101 and the first pin 102, wherein an anode of the diode 201 is connected to the reset pin 101 and a cathode of the diode 201 is connected to the first pin.
Because the diode has the characteristics of forward conduction and reverse cut-off, when the current state of the first pin is changed, the current state of the reset pin can be changed.
The integrated control unit 100 is capable of being reset upon detecting an excessive change in the current state of the reset pin 101.
In the invention, the circuit module comprises an integrated control unit provided with a reset pin and a first pin and a control module arranged between the reset pin and the first pin, and the control module can change the current state of the reset pin when the current state of the first pin changes, so that a user does not need to manually check the state of the first pin to determine whether the circuit module has a fault; and because the integrated control unit can reset when detecting that the current state of the reset pin is changed, the invention can automatically control the circuit module to reset, has higher intelligence and improves the user experience.
As another implementation form, the control module may specifically be a controller; then, the control module may detect whether the current state of the first pin changes in real time, and control the reset pin to change the corresponding state when detecting that the current state of the first pin changes.
Specifically, when the current state of the first pin changes, the control module may change the current state of the reset pin. For example, the current state of the reset pin and the current state of the first pin are changed in the same way, or the current state of the reset pin and the current state of the first pin are changed in different states.
In the present invention, the integrated control unit may specifically include a storage unit for storing data related to the circuit module; the integrated control unit may be specifically configured to control the reset of the storage unit when detecting that the current state of the reset pin has changed, so that the circuit module can operate normally.
The storage unit is configured to store data related to the circuit module, and specifically may store hardware configuration data information related to functions that can be implemented by the circuit module.
For the convenience of understanding, the invention is described with a specific application example to a circuit module; referring to fig. 3, the integrated control unit may be a PCH (integrated south bridge) chip, and the control module is a diode; with reference to fig. 3, the circuit module includes a PCH chip 100 and a diode 201;
the PCH chip is provided with a reset pin 101 and a first pin 102, specifically, the reset pin may be an RTCRST pin of the PCH chip, and the first pin may be an SRTCRST pin of the PCH chip.
The cathode of diode 201 is connected to SRTCRST pin 102 and the anode of diode 201 is connected to RTCRST pin 101.
The RTCRST pin 101 is adapted to be connected to the first circuit block 300 and the SRTCRST pin 102 is adapted to be connected to the second circuit block 400.
As a specific implementation form, the first circuit module may include a first resistor R1 and a first capacitor C1, where one end of the first resistor R1 is connected to the power supply voltage VBRT, the other end of the first resistor R1 is connected to one end of the first capacitor C1, and the other end of the first capacitor C1 is grounded; the second circuit block may include a second resistor R2 and a second capacitor C2, wherein one end of the second resistor R2 is connected to the power voltage VBRT, the other end is connected to one end of a second capacitor C2, and the other end of the second capacitor C2 is grounded.
The RTCRST pin 101 is specifically connected between the first resistor R1 and the first capacitor C1, and the SRTCRST pin 102 is specifically connected between the second resistor R2 and the second capacitor C2.
The first resistor and the second resistor can be resistors with larger resistance values, such as 20K Ω.
The capacitance values of the first capacitor and the second capacitor may be smaller capacitors, such as 1 μ F.
It should be noted that, in the prior art, the SRTCRST pin is easily over-contacted (short-circuited) with the housing of the electronic device during the assembly process of the electronic device, and the PCH chip plays a critical role in the booting of the electronic device, so long as the SRTCRST pin is over-short circuited, the electronic device cannot be booted.
For the problem, in the solution of the prior art, a user checks each circuit module of the electronic device one by one, and when it is determined that the PCH chip has a problem, the RTCRST pin is manually controlled to reset, so that the PCH chip is reset, and after the PCH chip is reset, the electronic device can be turned on.
Therefore, the prior art has the disadvantages of complicated operation and low intelligence in the solution for the problems.
In the invention, a control module, which is a diode in this embodiment, may be provided at the SRTCRST pin and the RTCRST pin. In a normal state, both the SRTCRST pin and the RTCRST pin are at a high level, and when the SRTCRST pin is in contact with the ground, the SRTCRST pin is changed from the high level to a low level; when the SRTCRST pin is no longer in contact with ground and thus returns from a low level to a high level, the RTCRST pin also returns from a low level to a high level due to the action of the diode.
The PCH chip is used for resetting when the pin RTCRST is detected to be restored from low level to high level.
It should be noted that the diode is only a specific implementation form of the control module, and in the present invention, the diode may also be replaced by a controller, and the controller detects the current state of the SRTCRST pin to control the current state of the RTCRST pin.
In this example, the PCH chip may specifically include a CMOS (Complementary Metal oxide semiconductor) memory for storing data related to the circuit module, and may specifically be used for storing data information related to the hardware configuration of the electronic device. When the electronic device is started, the data detail information stored in the CMOS memory needs to be used, and therefore, the PCH chip can be specifically used to control the CMOS memory to reset when it is detected that the RTCRST pin is restored from a low level to a high level, so that the electronic device can be started.
