Embodiment
The explanation of following embodiment is refer to the attached drawing, can be to the specific embodiment implemented to the example present invention.
The embodiment of the present invention one provides a kind of programming system, including：Cd-rom recorder, time schedule controller and it is connected to the burning
Record the gate-controlled switch between outside input/output interface supply voltage incoming line of device and the time schedule controller, it is described can
Control switch is used to input to before time schedule controller in outside input/output interface supply voltage, cut-off cd-rom recorder with it is described outer
The connection of portion's input/output interface supply voltage incoming line, and inputted in outside input/output interface supply voltage to sequential
After controller, the connection of conducting cd-rom recorder and the outside input/output interface supply voltage incoming line.
Specifically, refer to shown in Fig. 3, the cd-rom recorder of the present embodiment is with Serial Peripheral Interface (SPI) cd-rom recorder（Claim SPI burnings afterwards
Device）Exemplified by illustrate.Gate-controlled switch 3 is connected between SPI cd-rom recorders and the 3.3V voltage input lines of time schedule controller, is used
In before 3.3V control sources to time schedule controller, separate the 3.3V voltages of Serial Peripheral Interface (SPI) cd-rom recorder and time schedule controller
The connection of incoming line, and after 3.3V control sources to time schedule controller, turn on Serial Peripheral Interface (SPI) cd-rom recorder and sequential
The connection of the 3.3V voltage input lines of controller.Wherein, time schedule controller（TCON IC）Supply voltage include：1.2V
The outside input of kernel supply voltage, 1.8V DDR internal memories supply voltage and 3.3V/output interface supply voltage.
The embodiment of the present invention increases gate-controlled switch 3, by SPI cd-rom recorders output signal and TCON IC 3.3V power supply signals
Connection separated, when input 12V voltages, and according to the electrifying timing sequence needed for TCON IC by voltage conversion circuit point
Do not convert after obtaining 3.3V, 1.8V and 1.2V voltage, then turn on gate-controlled switch 3, SPI cd-rom recorder output signals are connected to
TCON IC respective pins, do not interfere with 3.3V, 1.8V and 1.2V voltage electrifying timing sequence needed for TCON IC, so as to avoid because
Electrifying timing sequence needed for different TCON IC it is different and caused by show unusual condition.
It is the pin schematic diagram of the signal connecting interface controller of SPI cd-rom recorders and circuit board referring again to shown in Fig. 4,
Wherein the 1st pin, output signal CON1, CON2 of the 10th pin need to convey by TCON IC 3.3V voltage input lines
To TCON IC 3.3V power supply control pins.Such as foregoing prior art, when not increasing gate-controlled switch, the interface of SPI cd-rom recorders
The 1st pin, the 10th pin of controller are connected directly between in TCON IC 3.3V voltage input lines, CON1, CON2 two-way
Output signal persistently conveys, and is supplied so as to cause the 3.3V voltages from SPI cd-rom recorders to be also continuously applied to TCON IC 3.3V
Electric control pin, the TCON IC for needing to be later than 1.2V and 1.8V power demands for 3.3V, original power voltage supply order can quilt
Upset, cause abnormal show.
The gate-controlled switch 3 of the present embodiment is the voltage inputted according to time schedule controller IC 3.3V voltage input lines,
The cut-off or the chip of conducting that control SPI cd-rom recorders are connected with time schedule controller IC 3.3V voltage input lines.For another example Fig. 5
It is shown, the pin of gate-controlled switch and TCON IC annexation are shown, wherein, V+ pins are supply voltage pin, are connected to
TCON IC 3.3V voltage input ends（VDD33）, for being powered for gate-controlled switch 3；IN1 and IN2 is control pin；NO1 and
NO2 is input pin, is connected respectively with the 1st pin of the interface controller of SPI cd-rom recorders and the 10th pin, receives respectively
CON1, CON2 two-way output signal；COM1 and COM2 is output pin, is connected with TCON IC power supply control pin.Work as control
When pin is not received by the time schedule controller IC voltage of 3.3V voltage input lines, the first input pin NO1 and first is defeated
Go out between pin COM1 and separate, separate between the second input pin NO2 and the second output pin COM2；When control pin receives
During the 3.3V voltages of time schedule controller IC 3.3V voltage input lines, the first input pin NO1 and the first output pin COM1
Between turn on, turned between the second input pin NO2 and the second output pin COM2.So, supplied in the 3.3V needed for TCON IC
When piezoelectric voltage does not input, control the pin IN1 and IN2 of gate-controlled switch 3 do not receive voltage, make the first input pin NO1 and
Separate between one output pin COM1, separate between the second input pin NO2 and the second output pin COM2, from SPI burnings
CON1, CON2 two-way output signal of the interface controller of device can not reach TCON IC.In the 3.3V power supplies needed for TCON IC
When voltage has inputted, control the pin IN1 and IN2 of gate-controlled switch 3 receive 3.3V voltages, so that the first input pin NO1
Turn on, turned between the second input pin NO2 and the second output pin COM2, from interface between the first output pin COM1
CON1, CON2 two-way output signal of controller are just transported to TCON IC, and so, CON1 and CON2 signals can not possibly be earlier than
3.3V is input to TCON IC, so TCON IC electrifying timing sequences will not be caused to change and cause exception.
Corresponding to the embodiment of the present invention one, the embodiment of the present invention two provides a kind of method for burn-recording, implements applied to the present invention
The programming system of example one, the method for burn-recording include：

The connection of the outside input of controller/output interface supply voltage incoming line.
Wherein, the gate-controlled switch includes the confession of two input pins being connected with the cd-rom recorder and time schedule controller
Two connected output pins of electric control pin and be connected to time schedule controller outside input/output interface supply voltage it is defeated
Enter two control pins at end；
The control pin separates respectively when being not received by outside input/output interface supply voltage of time schedule controller
First input pin and the first output pin, the second input pin and the second output pin；And receiving time schedule controller
Outside input/output interface supply voltage when, be respectively turned on the first input pin and the first output pin, the second input pin
With the second output pin.
Wherein, the Serial Peripheral Interface (SPI) cd-rom recorder includes interface controller, the interface controller include respectively with institute
State two connected signal output pins of two input pins of gate-controlled switch；
