The process of the preset write sequence then carried may include: to obtain setting for all LCD registers in first write sequence
The first order sequence of standby mark；By it is described put in order in the preset write sequence all devices identify arrangement it is suitable
Sequence is compared, and judges whether the first order sequence meets putting in order in the preset write sequence;If meeting,
Then follow the steps S202；If not meeting, directly determine that the first write-in rule and preset write-in rule are inconsistent.
If S300, inconsistent, said write operation is filtered.
Specifically, the filtering said write operation, which refers to operating said write, deletes, and does not execute described write
Enter operation.It filters out in this way, realizing configured with the write operation inconsistent with the preset write-in rule, so that described write
Entering operation can not modify to the setting of LCD, be effectively reduced LCD and be arranged by the probability of bug patch.
In the present embodiment, the method also includes:
If S400, consistent, said write behaviour are carried out to several LCD registers according to the first write-in rule
Make.
Specifically, since said write rule provides that write-in must be sequentially written at least two companies according to said write every time
Continuous LCD register, but in practical applications, it is understood that there may be a LCD register or write-in need to be only written in write operation
The operation LCD register to be written is discrete situation.Therefore, it is posted in one LCD register of write-in or discrete LCD
When storage, in order to make single LCD register can satisfy said write rule, it is adjacent to need to obtain one LCD register
LCD register value, be then written according still further to write sequence and one post LCD storage and LCD register adjacent thereto.
Illustratively, if it is described consistent, according to the first write-in rule to described in several LCD registers progress
Write operation specifically includes:
If S401, consistent, several LCD registers are grouped according to the serial relation in said write sequence, and point
The number of every group of LCD register is not obtained；
S402, when the number be greater than 1 when, according to said write sequence execute write operation；

S404, write operation is carried out to the LCD register and the first LCD register according to said write sequence,
Wherein, the value of the first LCD register write-in is the current value.
Specifically, in the step S401, what the serial relation grouping according in said write sequence referred to
It is that continuous LCD register is divided into one group according to said write sequence, discontinuous LCD register is respectively divided into one group.
The number is 1 or the value greater than 1, if a certain group of number is 1,1 LCD register of the grouping is several with remaining
LCD register is discontinuous；If a certain group of number is the value greater than 1, the grouping includes described several continuous LCD
Register.
In the step S402, when the number is greater than 1, the grouping is by least two continuous LCD registers
Composition will need the value being written to be sequentially written in described at least two continuous LCD registers in sequence.
In the step S403 and S404, when the number is equal to 1, the grouping only includes a LCD register.
The first LCD register refers to an adjacent LCD register of the LCD register.It can be the LCD register
Adjacent previous position LCD register, or the adjacent latter position LCD register of the LCD register.In the present embodiment
In, the adjacent previous position LCD register of the LCD register is set by the first LCD register.Due to making number one
LCD register adjacent previous position LCD register is not present, therefore when the LCD register makes number one, described the
One LCD register is the adjacent latter position LCD register of the LCD register.The current value is the first LCD register
Currently stored value.
It is described that write operation is carried out to the LCD register and the first LCD register according to said write sequence,
In, the value of the first LCD register write-in is that the current value specifically includes: judging whether the LCD register comes the
One；If the LCD register makes number one, the LCD first is written into the value for needing to be written according to said write sequence
Register, then the first LCD register is written into the current value；If the LCD register does not make number one, according to
First current value is written in the first LCD register for said write sequence, then the LCD is written in the value of the write-in of needs and is posted
In storage.In this way, being deposited by reading the current value of the first LCD register using the current value as the first LCD
Device needs the value being written, and so that it is formed one group of continuous two LCD register with the LCD register and is executed in sequence and writes
Enter operation, realizes the value for changing the LCD register while not changing the value of the first LCD register.
Said write is operated below by a specific embodiment and is further illustrated: several LCD register packets
It includes: 0001,0002,0005,0007,0008,0009, since 0002 and 0005 is discontinuous, 0005 and 0007 is discontinuous, therefore will
Several registers are divided into three groups, are respectively as follows: 0001,0002 for first group, and 0005 is second group, and 0007,0008,0009
For third group；Then the number of first group of LCD register is 2, and it is 3 that second group, which is the 1, the 3rd group, illustrates that described first group has 2
A continuous LCD register group is at described second group only includes 1 LCD register, and the third group is posted by 3 continuous LCD
Storage composition.Due to described first group and third group be by least two continuous LCD register groups at, be written
When, directly the value being written will be needed to be sequentially written in several continuous LCD registers according to write sequence.That is, writing
It is fashionable, it is sequentially written in 0001 and 0002 value in sequence, in sequence the value of write-once 0007,0008 and 0009.It is writing
