Apparatus and method for acquiring identification information when a bus reset occurs

摘要

An apparatus and a method for acquiring identification information when a bus reset occurs are provided. The apparatus and the method for acquiring identification information when a bus reset occurs to control a slave device without an error by acquiring the new identification information (e.g., a PHY ID) by adjusting the power state of a slave device when a bus reset occurs in slave devices existing in an IEEE 1394 A/V network, and to reduce the power consumption by changing the power state to the power-standby state after acquiring the basic information of the slave device.
