Identification code address date in single-chip microcomputer；Calculated according to default custom algorithm and generate the first registration code.
In the present embodiment, the setting of the first registration code causes single-chip microcomputer that note is had to pass through after the completion of program burn writing
Volume could once be used.As each single-chip microcomputer corresponds to a unique identification code, used according to the address date of the identification code
Family can generate first registration code according to self-defining algorithm.
S12：Obtain the second registration code of the extraneous input of single-chip microcomputer.
Wherein, the second registration code of the extraneous input of single-chip microcomputer is obtained, including：Obtain by the button of single-chip microcomputer itself or
Second registration code of communication interface input.
From above-mentioned embodiment, if it is desired to be accomplished by once being registered using the single-chip microcomputer, due in above-mentioned step
In rapid, single-chip microcomputer is calculated by itself default algorithm and generates the first registration code, and extraneous input the is accomplished by when registering
To be matched with the first registration code, if active user is single-chip microcomputer production authorized user, which necessarily knows the to two registration codes
Two registration codes；If active user is not single-chip microcomputer production authorized user, the second registration code is being unaware of.Wherein, user can be with
Second registration code is input in single-chip microcomputer to be registered by the communication interface of button or single-chip microcomputer.
S13：Judge that whether with the first registration code of the second registration code is consistent.
S14：If so, the authority of the plug-in of operation single-chip microcomputer is then given, i.e. current monolithic machine can normally run journey
Sequence, performs function of the MCU.When the second registration code and consistent the first registration code is judged, the first registration code can also be stored, if
Judge that the second registration code and the first registration code are inconsistent, then do not store any registration code so that single-chip microcomputer enters running protection mould
Formula, until second registration code and the first registration code of input are consistent.
S15：If it is not, then forbidding running the plug-in of single-chip microcomputer.Default single-chip microcomputer protected mode can be entered, this
When, single-chip microcomputer can not normal operation program.
In the present embodiment, single-chip microcomputer generates first according to itself unique identifier address date and default algorithm
Registration code, and if want just be registered using the single-chip microcomputer, that is, being input into the second registration code is registered, and only works as input
The second registration code it is consistent with the first registration code for prestoring when just represent and succeed in registration, the now plug-in to single-chip microcomputer
Operation mandate is carried out, even if so the non-acquisition of technology mandate of lawless people have read the contents of program in single-chip microcomputer, to single-chip microcomputer
Copied, but in the case where the computational methods of the first registration code are not known, be cannot to learn and the first registration code-phase
The second consistent registration code, also cannot just carry out registration and use the single-chip microcomputer, which greatly enhances the security performance of single-chip microcomputer,
Avoid unauthorized personnel to copy single-chip microcomputer.
Refer to Fig. 2, the single chip computer architecture schematic diagram that Fig. 2 is provided by a kind of specific embodiment of the invention.

Being registered in piece machine.
Further, the single-chip microcomputer, also includes：Memory module, for judging the second registration code in the first judge module
When consistent with the first registration code, the first registration code is stored.When the second registration code and consistent the first registration code is judged, can also deposit
The first registration code is stored up, if it is determined that the second registration code and the first registration code are inconsistent, then any registration code is not stored so that single-chip microcomputer
Into running protection pattern, until second registration code and the first registration code of input are consistent.
In sum, single-chip microcomputer provided by the present invention and its control method, unique identifier of the single-chip microcomputer according to itself
Address date and default algorithm generate the first registration code, and if want just be registered using the single-chip microcomputer, that is, be input into
Second registration code is registered, and note is just represented only when the second registration code of input is consistent with the first registration code for prestoring
Volume success, now carries out operation mandate to the plug-in of single-chip microcomputer, even if so non-acquisition of technology mandate of lawless people is read
Contents of program in single-chip microcomputer, is copied to single-chip microcomputer, but in the feelings of the computational methods for not knowing the first registration code
Under condition, it is to learn second registration code consistent with the first registration code, also cannot just carries out registration and use the single-chip microcomputer,
Which greatly enhances the security performance of single-chip microcomputer, it is to avoid unauthorized personnel is copied to single-chip microcomputer.
Above a kind of single-chip microcomputer provided by the present invention and its control method are described in detail.Tool used herein
Body example is set forth to the principle and embodiment of the present invention, and the explanation of above example is only intended to help and understands this
Bright and its core concept.It should be pointed out that for those skilled in the art, without departing from the principle of the invention
