MICROCONTROLLER INPUT/OUTPUT CONNECTOR STATE RETENTION IN LOW-POWER MODES |
摘要 |
A microcontroller is operable in a low-power mode and includes one or more I/O connectors, as well as an I/O controller operable to provide control signals for controlling a state of a particular one of the I/O connectors. The I/O controller is powered off or deactivated during the low-power mode. The microcontroller also includes I/O connector state control logic operable to control the state of the particular one of the I/O connectors in accordance with the control signals from the I/O controller. The I/O connector state control logic includes I/O connector state retention logic that retains states of the control signals and maintains the particular I/O connector in a corresponding state in accordance with the retained control signals while the microcontroller is in the low-power mode. |
