Bus monitoring and controlling method, electronic device, chip, and storage medium

Abstract

This application relates to a bus monitoring and controlling method, an electronic device, a chip, and a storage medium. The method is applied to an integrated circuit device. The integrated circuit device monitors communication data between a master and a slave on an SPMI bus. If it is determined based on the communication data that a working state of the integrated circuit device is a first working state, and the SPMI bus is in an idle state, the integrated circuit device performs bus arbitration on the master by simulating the slave, performs bus arbitration on the slave by simulating the master, and controls switching of a switch module, so that the integrated circuit device is separately connected to the master and the slave. When it is determined that the master with the highest priority preempts the SPMI bus, the integrated circuit device sends supplementary data to the slave. After performing bus arbitration on the master and the slave, the integrated circuit device performs switching on the switch module. In this way, the following case can be avoided: A spike generated in a switching process of the switch module affects running of the SPMI bus. An external integrated circuit device implements control on data of the slave.
