[0004] Depending on the system design, the system design vendor will define various instructions for development. These instructions are referred to as embedded controller extension instructions, which are used to perform corresponding functions designed by various vendors, such as displaying the operating temperature of the main system 10, controlling the screen flip, and the like. However, the electronic device 1 supporting ACPI may be transmitted through the embedded controller input/output port 104 simultaneously by the embedded controller standard command and the embedded controller extension command, and 094135079 Form No. A0101 Page 4 of 18 Page 0993302438-0 ΡΓ333146 Fixed the replacement page on August 25, 099, causing an instruction conflict. In the prior art, a global lock or a critical section is used for resource sharing to avoid conflicts between the embedded controller standard instructions and the embedded controller extension instructions. However, global locks and critical intervals will appear to be busy waiting for instructions, resulting in system efficiency degradation.

[Embodiment] Please refer to the third figure, which discloses a connection block diagram of the pure controller 22 of the main system 20 in the electronic device 3 of the present embodiment. The electronics can be used as notebooks, tablets, and computers. For convenience of description, the following description will be made by taking a notebook computer as an example. The embedded controller 22 includes a keyboard control interface module m, an embedded control interface module 224, and an extended interface module 226. The keyboard control interface module communicates with the main system 20 through the keyboard controller input/output port 202, and the keyboard controller input/output port 2p2 adopts 60h/64h埠 for transmitting the operation command of the input terminal 14” embedded control interface. The module 224 communicates with the host system 20 via the embedded controller input/output port 204. The embedded controller wheel input/output port 204 is 62h/66h埠 for transmitting embedded controller standard commands supporting the ACPI standard. The extended interface module 226 communicates with the host system 20 via a dedicated input/output port 206. The extended interface module 226 can be a hardware interface module or a program virtual interface module, and the form number A0101 is 6 pages/18 pages 0993302438-0 p33146. The verification page is described on the August 25, 099 The extended interface module 226 and the host system 20 perform the transfer of the back-in controller extension instructions. [0016] The main system 20 transmits the enemy controller extension command to the embedded controller 22 via the dedicated input/output object 6. The drum controller 22 receives and executes the lost controller extension command. After the execution of the instruction is completed, the add-on controller 22 feeds back the instruction execution result to the main system 20 through the extended interface module 226 and the dedicated input/output port 206. [0017] Since the main system 20 can directly access the embedded controller 22 through the dedicated input/output port 2〇6, the dedicated input/output port 206 is turned off when the extended interface module 226 is not working. status. When the main system 2 has an embedded extension instruction that needs to be transmitted, the dedicated input/output object 6 is turned on by the interrupt mode. The embedded controller 22 uses polling or interrupting to know whether the extended interface module 226 has received an instruction. The polling mode is when the intercept controller 22 periodically detects whether the extended interface module 226 receives the command. The interrupt mode is that after the extended interface module 226 has received the command, the extended interface module 226 sends an interrupt signal to inform the embedded controller 22 that the command has been received. The enemy controller 22 knows that the extended interface module m has received the command and executes the command. [0018] 094135079 Refer to the fourth figure' for the operation diagram of the extended interface module 226 of the electronic device 3 shown in the third figure. When the dedicated wheel/input (4) is turned on and the extended interface module 226 is initialized, the following steps are performed: First, the extended interface module 226 receives the command of the host system 20 through the dedicated input/output port 2〇6 (steps) 30). After the instruction is received, the extended interface module 226 status flag is set, which indicates that the extended interface module 226 is in a "busy" state (step 31). After the setting is completed, the embedded control form number A0101 page 7/18 pages 0993302438-0 I. On August 25, 099, a modified page controller 22 analyzes the instructions received by the extended interface module 226, and according to the instruction requirements. Load the corresponding application (step 32). The loaded application program starts running and implements the command corresponding function of the main system 20 (step 33). After the execution of the application is completed, the embedded controller 22 feeds back the execution result to the main system 20 (step 34). Finally, the extended interface module 226 status flag is cleared (step 35), and the flow ends. [0019] The purpose of setting the extended interface wedge group 226 status flag is that when the extended interface module 226 has not processed the current work task, the main system 20 can learn to expand by detecting the extended interface module 2 2 6 status flag. The interface module 2 2 6 is busy, at which time the main system 20 has to wait for the flag to be cleared before transmitting the next instruction. [0020] Referring to FIG. 5, the working flow chart of the extended interface module 226 of the embedded controller 22 is called for the main system 20 of the electronic device 3 shown in the third figure. The following steps are included: when the main system 2 When the lost controller extension command needs to be transmitted, the main system 20 generates an interrupt signal and turns on the dedicated input/output port 206 (step 42). The embedded controller 22 first detects whether the extended interface module 226 is valid (step 43). If the extended interface module 226 is invalid, the embedded controller 22 feeds back the invalid state of the extended interface module 226 to the primary system 20 (step 4 4). ). The main system 20 receives the feedback information, and knows that the extended interface module 226 is temporarily unable to receive the command, and closes the dedicated input/output port 206 (step 49), and the flow ends. If the extended interface module 226 is active, the host system 20 transmits the instructions to the extended interface module 226 (step 45). The embedded controller 2 2 analyzes the instructions received by the extended interface module 2 2 6 , loads the corresponding application of the instruction and runs (step 46). During the running of the application, the embedded controller 22 detects that the application is 094135079. Form No. A0101 Page 8 / 18 pages 0993302438-0 ^ 333146 [0022] [0023] [0025] [0025] [0026] 094135079 0S3Aug. 25, Amendment Replacement Page No Execution Completed (Step 47) ^ If not completed, continue execution. If so, the embedded controller 22 feeds back the execution result to the main system 2 (step 48). After the feedback is completed, the main system 2 turns off the dedicated input/output port 206 to invalidate the extended interface module 226 (step 49), and the process ends, the method for avoiding the command transmission conflict and the electronic device 3 thereof, through an extended interface. The module 226 and a dedicated input/output port 2〇6 respectively transmit the embedded controller extension instruction and the embedded controller standard instruction supporting the ACPI by different channels, thereby avoiding instruction transmission conflicts. At the same time, it also reduces the appearance of the command busy green waiting situation and improves the efficiency of the main system. In addition, when the main system 20 does not call the extended interface module 226, the dedicated input/output port 206 is in a closed state to ensure the communication security of the embedded controller 22. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
