A method of performing a burst read access at a memory device using a multiplexed data/address bus and a control signal including transferring a first portion of address information in a first phase via the multiplexed data/address bus to the memory device; transferring second portion of address information in a second phase via a multiplexed data/address bus to the memory device; transferring a series of data words from the memory via the multiplexed data/address bus; toggling the state of the control signal at the memory device as each data word is transferred; and suspending the transfer of the series of data words from the memory via the multiplexed data/address bus and the toggling of the state of the control signal.

Multiphase addressing method for transferring address information

A data handling device capable of operating in a system in which two or more devices are connected by a data bus for the transmission of communications therebetween, the data bus having two or more data lines and the device having: two or more data bus connectors, each for connection to a respective data line of the data bus; an identity acquisition unit capable of functioning in a first mode of operation of the device to receive data transmitted over the data bus and in response to the order in which the bits of one or more data words of a predetermined form are received on the data bus connectors during the first mode of operation determine an identity for the device and store the identity in an identity store of the device; and a data handling unit capable of functioning in a second mode of operation of the device to handle communications transmitted over the bus and that specify the identity stored in the data store as a destination.
