Problems solved by technology

[0003] The current sleep wake-up method is to achieve two-way wake-up by adding a custom sleep indicator signal and wake-up signal. This method takes up more hardware resources due to the addition of hardware signals outside the serial port communication.

Abstract

The invention discloses a method for awaking sleep of chip modules, which adopts most common serial ports for communication among the chip modules to carry out awaking control, and sets and controls an RTS port and a CTS port of a UART serial port. Without increasing a new hardware signal port, the method can realize bidirectional sleep awaking between the two chip modules so as to save the cost and improve the efficiency.

Description

technical field [0001] The invention relates to the communication field of a chip module, in particular to a method for awakening a chip module from sleep. Background technique [0002] Embedded devices have been applied to various fields now. Existing communication devices generally have multiple chip modules, and the module unit composed of each chip module and its peripheral circuits is equivalent to a relatively independent system. In the era of energy shortage, in order to reduce power consumption, each chip module usually turns off the main clock to enter the sleep state when it is idle, and when an external event occurs, the chip module will be woken up and return to the normal state. Since the current chip modules enter the sleep state separately, in order to ensure the safety and effectiveness of the communication between the modules, it is necessary to adopt a sleep wake-up method and mechanism to wake up the chip modules in the sleep state. [0003] The current s...
