Description of the Invention: [Technical Field of the Invention] The present invention relates to a power management technique, and more particularly to an electronic device having a power management mechanism. [Prior Art] According to Moore's law, Gordon Moore (G〇rden screams that the number of transistors that can be accommodated in the integrated circuit (10) is about eight times-fold per month. It will also increase - times, and currently a integrated circuit (icu already includes millions of transistors and copper wires, this complex = integrated circuit (10) structure will relatively increase the power consumption. In addition, because the computer speed and function requirements = seeking to improve, so the power supply inside the electronic device = relative central processing unit (CPU) for the power management mode of the branch::: ten is also more important; In addition to the PC system or the servo system, the embedded system also benefits the technology to achieve energy-saving effects, enabling the use of embedded systems and other related electronic products. It can also have a longer time to use the central processing unit of the two = electronic device, the g-type, and not all of the operating processors can enter the sleep mode (deeps eepm〇de) of 4 = Therefore = child, set Machine time and system utilization, not to mention the design of a large number of bullying systems, which are used in a large number of personal digital assistants PDAs, various network related devices, mobile phones, digital cameras, digital photography 19257 5 1313801, and In the system of digital TV and other related electronic products, the degree of computational processing power is more important. However, because each chip designer = 疋 package materials, the amount of materials in the package, so that the operating area of the two sides The problem of sleep mode is generated, which will affect the efficiency of the system and the reliability of the system when the power is too low. Some central processing units (such as Samsung 244〇 or s_ung24i()) that cannot enter the sleep mode are the platform. In the case of the system, the if::: quantity is too low, because it will not enter the sleep mode by itself, but the battery is turned off when the battery is too low: the clock is fully powered. When the power is turned on, the system will be discovered. : 2 = η * " 6 Μ 则 则 则 咖 咖 咖 ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; , , , , , , , , , , , , , , , Out of the second two = solve the problems existing in the previous technology, and develop: the technical solution of the source of the Lvli mechanism to effectively prevent the loss of data managed by the immediate group when the power supply of the electronic device is suddenly turned off. It is precisely the subject that needs to be solved urgently. SUMMARY OF THE INVENTION In view of the disadvantages of the prior art, the main object of the present invention is the power supply of the electronic device. The purpose of effective management is to provide a power management mechanism to avoid the loss of data managed by the clock module when 19257 6 1313801 is suddenly turned off due to the power supply of the electronic device.
