【発明の名称】無電力供給状態での集積回路のバス動作
Document Type and Number:
Japanese Patent JP2003536301
Kind Code:
A
Abstract:
A circuit configuration applicable to systems such as consumer electronics devices enables communication between components such as integrated circuits connected to the bus. According to an embodiment, the RUN power supplies are turned to an OFF state in response to a fault condition. An interface circuit associated with an integrated circuit coupled to the bus controls the loading on the bus caused by the interface circuit and the integrated circuit such that communication between devices on the bus can continue. Therefore, even when a fault condition results in the loss of the RUN power supplies, a command can be transmitted over the bus from a first integrated circuit in a powered state to a second integrated circuit in the powered state while a third integrated circuit connected to the bus is in an unpowered state.
