Internal integrated circuit device of internal integrated circuit system and control method thereof

The present invention discloses a device of an internal integrated circuit system and a control method thereof. The control method is used for a first device of the internal integrated circuit system. The internal integrated circuit system includes a microcontroller unit. The control method includes: receiving a first indication from the microcontroller unit of the internal integrated circuit system, wherein the first indication configures the first device from a slave mode to a master mode; polling the first device itself for status information of the first device when the first device is in the master mode; determining whether the status information of the first device matches a target status after polling; and determining to perform a parameter adjustment on a second device of the internal integrated circuit system when determining that the status information of the first device matches the target status. 本发明公开了种内部集成电路系统的装置及其控制方法，该控制方法用于内部集成电路系统的第装置，该内部集成电路系统包括单片机，该控制方法包括从该内部集成电路系统的该单片机接收第指示，该第指示设定该第装置由从机模
