NETWORK CONTROLLER
Document Type and Number:
Japanese Patent JP2019106724
Kind Code:
A
Abstract:
To provide a technique in which selective wakeup of a desired node via a transmission path used for communication is achieved and power consumption in sleep mode is further reduced.SOLUTION: A feed control unit (21), when receiving a sleep instruction from a communication execution unit in a wake-up mode, shifts an operation mode to a sleep mode by turning off a first feed output and turning on a third feed output. When a signal is detected by a signal detection unit (22) in the sleep mode, a wakeup signal reception/processing unit (23) is activated by turning on the second power supply output. When it is determined that wakeup is required by the activated wakeup signal reception/processing unit, the first feed output is turned on, and an operation mode is shifted to the wakeup mode by turning off the second feed output and the third feed output.SELECTED DRAWING: Figure 2
