Abstract

The embodiment of the invention provides slave equipment and a method for configuring a line sequence of an MIPI of the slave equipment. The method comprises the following steps: the step a, writing a preset first line sequence of the MIPI of the slave equipment into a first register; the step b, setting a second register as a first value, enabling all MIPI circuits of the slave equipment based on the first value, and enabling pull-up resistors respectively corresponding to all the MIPI circuits; the step c, receiving an initialization instruction sent by the host equipment; and the step d, if the initialization instruction comprises a second line sequence of the MIPI of the host equipment, writing the second line sequence into the first register, setting the second register as a second value, and configuring the line sequence of the MIPI of the slave equipment based on the second value and the second line sequence. According to the technical scheme provided by the embodiment of the invention, a special pad does not need to be arranged for configuring the line sequence of the slave equipment MIPI, so that pad resources on the slave IC are saved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a slave device and a method for configuring its MIPI line sequence. Background technique [0002] Mobile Industry Processor Interface (MIPI) is an open standard and specification developed by the MIPI Alliance for mobile application processors, which is used to standardize the internal interfaces of mobile devices (also called slave devices) as standard internal interfaces , which includes a camera interface (Camera Serial Interface, CSI), a display interface (Display Serial Interface, DSI), and a radio frequency interface (Digital Radio Frequency, DigRF), etc. An external device (which may also be referred to as a master device) that communicates with the standard internal interface of the slave device contains a processor that controls communications with the slave device. [0003] The standard internal interface of the mobile device has a physical layer module (such as...
