Problems solved by technology

Under this pin configuration method, before the sub-mode chip is powered on, the CPU of the sub-mode chip may be in a leakage state because the output pin on the main mode chip is configured as a high-level output, resulting in dual-mode The phenomenon that the mobile phone cannot be started occurs

Embodiment Construction

[0013] Such as figure 1 As shown, it is a structure diagram of a preferred embodiment of the timing control system (hereinafter referred to as the control system) of the present invention. In this embodiment, the output pin 11 of the main mode chip 1 of the dual-mode mobile phone 100 is connected to the input pin 21 of the secondary mode chip 2, and the input pin 12 of the main mode chip 1 is connected to the secondary mode chip 2 output pin 22. The control system 10 runs the main mode chip 1 of the dual-mode mobile phone 100, and is used to control the main mode chip 1 and the secondary mode chip 2 of the dual-mode mobile phone 100 according to the dual-mode interaction when the dual-mode mobile phone 100 is started. The protocol configures the timing of the pins (that is, the output pins 11, 22 and the input pins 12, 21).

[0014] It should be noted that the dual-mode interaction protocol described in this embodiment may be based on GSM (global system for mobile communicat...

Abstract

The invention provides a time sequence control system used for controlling a configuration time sequence of pins of a main mode chip and a minor mode chip of a dual-mode handset. Before the minor mode chip is powered on, the system sets an output pin of the main mode chip to be of low level and configures an input pin of the main mode chip according to a dual-mode interaction protocol and after input pin and out pin configuration of the minor mode chip is completed according to the dual-mode interaction protocol, the main mode chip is controlled to configure the output pin of the main mode chip according to the dual-mode interaction protocol. The invention also provides a corresponding time sequence control method. The time sequence control system and method are capable of preventing happening of a situation, in which a CPU of the minor mode chip leaks electricity, through adjustment of pin configuration so that a situation in which the dual-mode handset is incapable of normal start because the CPU of the minor mode chip leaks electricity is prevented from happening.

Description

technical field [0001] The invention relates to a control system and method of communication equipment, in particular to a timing control system and method of a dual-mode mobile phone. Background technique [0002] A dual-mode mobile phone needs to be composed of a main-mode chip and a secondary-mode chip. In order to realize information interaction between the two chips, some fixed connection pins are needed to connect the main-mode chip and the secondary-mode chip. Connected pins can be summarized in two categories, output pins and input pins. When the mobile phone is started, the output and input pins need to be configured according to the dual-mode interaction protocol, for example, a certain pin on the main mode chip is configured as a high-level output or a low-level output according to the dual-mode interaction protocol. [0003] In the existing pin configuration method, when the main mode chip is powered on, the output and input pins on the main mode chip are direct...
