Abstract:
1. An address sharing method comprising: coupling at least two peripheral devices to a communication system; assigning a common configuration address to each peripheral device; assigning a unique range of configuration registers to each peripheral device; sending an address command to the common configuration address; sending a register command addressing a configuration register at the common configuration address; monitoring the address and register commands by each peripheral device; identifying the common configuration address; identifying a configuration register address as being within the unique range of assigned configuration registers for a single peripheral device; issuing a response from the single peripheral device having the identified configuration register within the unique range of assigned configuration registers for the single peripheral device, wherein the single peripheral device will not issue a response until its common configuration address and the configuration register address are within the range of the assigned configuration registers to prevent contention among the at least two peripheral devices; and wherein the step of issuing a response from the single peripheral device includes sending a synchronization code from the single peripheral device to the communication system.
