Abstract
A system includes a bus system to connect a number of components in a chain-like structure. A first control device (e.g., microcontroller or microprocessor) is configured to control the components in a first mode of the system. A second control device (e.g., microcontroller or microprocessor) is configured to control a first subset of the components in a second mode of the system.
Claims20
A method of operating an integrated circuit component, the method comprising:
- transitioning the integrated circuit component from a passive state to an active state in a first operational mode by
- receiving a wake request data signal at a first port of the integrated circuit component,
- transmitting the wake request data signal from the first port of the integrated circuit component to a second port of the integrated circuit component, and
- transitioning the integrated circuit component from the passive state to the active state in the first operational mode after receiving the wake request data signal from the first port;
- and
- transitioning the integrated circuit component from the passive state to the active state in a second operational mode by
- receiving the wake request data signal at the second port of the integrated circuit component,
- transmitting the wake request data signal from the second port of the integrated circuit component to the first port of the integrated circuit component, and
- transitioning the integrated circuit component from the passive state to the active state in the second operational mode after receiving the wake request data signal from the second port.
