Embodiment Construction

[0028] As mentioned earlier, in the USB Type-C specification, a USB Type-C cable has USB Type-C plugs at both ends, and the device they plug into may have a Dual Role Port (DRP).

[0029] In the prior art, the time parameters of USB Type-C DRP are specified in the protocol in detail. The DRP cycle can be set, and in each DRP cycle, a part of the time is set for the master device A to work, and it is compared with the DRP The quotient of the period is the duty cycle, so as to detect whether there is a device plugged in during the working time of the master device A.

[0030] refer to figure 1 , figure 1 It is a schematic diagram of a USB Type-C DRP cycle in the prior art.

[0031] Specifically, in the USB Type-C DRP cycle A (USB Type-C DRP timing, tDRP), period B is the time occupied by DcSRC.DRP. It can be understood that the quotient of period B and DRP cycle A is the duty cycle.

[0032] Wherein, the DcSRC.DRP is used to indicate the percentage of time that a DRP shall a...

Abstract

The invention discloses a dual-action port USB Type-C interface device and a configuration method thereof. The device comprises a digital core controller and a Type-C module, the Type-C module comprises: a detection period register in a sleep mode used for triggering the Type-C module to enter a sleep mode when the indication level is received to indicate that a CPU enters the sleep mode, and timeparameters of a USB Type-C dual-action port are configured to be a first period and a first duty ratio in the sleep mode; and the detection period register in the intrinsic mode is used for triggering the Type-C module to enter the intrinsic mode when the indication level is received to indicate that the CPU enters the working mode. According to the scheme, the power consumption of the USB Type-Ccan be reduced, and the power saving requirement is met.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a dual-port USB Type-C interface device and a configuration method thereof. Background technique [0002] Universal Serial Bus (USB) is not attached to Type-C (Type-C), as a USB interface standard, it supports USB Type-C plugs that can be plugged in front and back, so that users can have a better user experience. [0003] In the USB Type-C specification, a USB Type-C cable has USB Type-C plugs at both ends, and the devices they plug into may have three "roles": slave device port (Up Facing Port, UFP), master device Port (DownFacing Port, DFP) and dual role port (Dual Role Port, DRP). For DRP, when the two DRPs of the USB Type-C cable are connected to the master device (Source) A and the slave device (Sink) B respectively. [0004] In the prior art, the time parameters of USB Type-C DRP are specified in the protocol in detail. The DRP cycle can be set, and in each DRP cyc...
