International Classification:

G06F 1/04

US Classification:

368155

Abstract:

Various apparatuses, methods and systems for a real time clock are disclosed herein. For example, some embodiments provide a real time clock including a clock generator having a first input connected to a clock signal and a second input connected to a time set signal. The clock generator produces a time change signal at an output of the clock generator. Counters, each adapted to track a different unit of time, are connected to the time change signal. The clock generator is adapted to generate a pulse on the time change signal for each pulse of the time set signal, and to generate separate pulses on the time change signal for consecutive pulses on the clock signal and the time set signal.

Abstract:

An adaptive USB port controller is disclosed. In an exemplary embodiment, a system comprises a source, a power adapter, a USB port controller, a USB plug and cable, and a device. In one example, the device includes a rechargeable battery. After connecting the device to the USB port controller via the USB plug and cable, a reconfigurable module within the USB port controller sets a power mode by: (1) configuring an impedance network to present impedance modes that indicate available power modes, (2) detecting voltages on one or more of the USB conductors in response to each impedance mode, and (3) comparing the detected voltages to reference voltage levels to set one of multiple power modes. The reconfigurable module then controls the power adapter to transfer power according to the determined power mode.
