Abstract

The invention discloses a communication control method and a communication circuit. The communication control method controls data exchange between a complex programmable logic device CPLD and a central processing unit, and the complex programmable logic device is connected with the central processing unit through an LPC bus. The communication control method comprises the following steps: firstly,the central processing unit acquires a cyclic initial signal of the LPC bus; when the obtained cyclic initial signal is in a preset level state, the current working state of the LPC bus is obtained;and a data writing or data reading action on the complex programmable logic device CPLD is carried out according to the current working state of the LPC bus. According to the scheme, the technical problem that the EC chip and the IO chip are high in cost is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication control method and a communication circuit. Background technique [0002] In the prior art, a computer is generally composed of an EC (main control chip) and a SUPER IO (Super I / O chip is also called an I / O chip), wherein the I / O chip is responsible for providing serial and parallel interfaces and a floppy disk drive control interface . In the case of the United States' blockade of chip exports, the sources of EC (main control chip) and I / O chips are reduced and the cost is rising. Therefore, it is urgent to find a new I / O communication method to reduce the cost of industrialization. Contents of the invention [0003] The main purpose of the present invention is to propose a communication control method aimed at solving the technical problem of high cost of EC chips and IO chips. [0004] In order to achieve the above object, the present invention propos...
