摘要: A physical layer interface for an IEEE-1394 serial bus node includes multiple port transceivers connected to respective buses. controller, a link and the transceivers, supplies control signals encoder/decoder performing data conversion between repeater repeating traffic transceivers. speed setting circuit is provided storing lowest value of transmission speeds in register map controller as top node. The arranged read stored from register, receive another begin packet at lower one received values.
