    Abstract: Some embodiments include apparatuses and methods having a node to couple to a serial bus, and a controller to provide a control signal to one of a first circuit path and a second circuit path in order to change electrical termination of a signal at the node between a first electrical termination through the first circuit path during a first mode of the controller and a second electrical termination through the second circuit path during a second mode of the controller. The controller can be arranged to provide the control signal to the first and second circuit paths during the first and second modes without providing another control signal from the controller to the first and second circuit paths during the first and second modes.

    Abstract: Three components are used to adjust the CPU peak power based on the USB TYPE-C device states. These components include operating system (OS) Peak Power Manager, USB TYPE-C Connector Manager, and USB TYPE-C Protocol Device Driver. The USB TYPE-C Connector Manager sends a synchronous request to the OS Peak Power Manager when a USB TYPE-C power sink device is attached or detached, and the USB TYPE-C Protocol Device Driver sends a synchronous request to the Peak Power Manager when the power sink transitions device state. The Peak Power Manager takes power budget from the CPU when the USB TYPE-C connector is attached to a power sink and is active (e.g., high power device state), and gives back the power budget to the CPU for performance when the USB TYPE-C connector is either detached or the attached and power sink device is idle (lowest device state).
