ABSTRACT:
A peripheral device, connected to an address bus, which has yet to be assigned an I/O address has a pin connected to a configuration select output of a control logic circuit (or a CPU). The peripheral device is reset upon start-up of the system and is not yet required to respond to normal bus accesses or traffic. The CPU analyzes the available addresses in the address space and selects an available I/O address for assignment to that peripheral device. In one embodiment, the CPU then sends a serial bit stream containing the selected I/O address to that peripheral device over a configuration select line. In another embodiment, the CPU asserts a configuration select signal to the peripheral device. The CPU then transmits the selected I/O address to the peripheral device on the address bus. The transmitted I/O address is then stored in the peripheral device, and the device will now respond to this I/O address during subsequent operation of the system. In this way, the peripheral device is assigned an I/O address prior to that device having to interact or become active on the address bus or in the I/O address space.
