ABSTRACT:
An electronic system has multiple identical Input/Output (I/O) devices which are all connected in daisy-chain fashion on a serial bus. At power-up or reset, the I/O device at the end of the chain configures itself as Device 0, and outputs data to the next device which configures it as Device 1. Device 1 then outputs data to the next device which configures it as Device 2, and so on until all the I/O devices have been assigned a device number. In this manner the I/O devices are configured to unique addresses without additional external pins or intervention by the System Controller, minimizing package size and eliminating logic which would otherwise be required if the System Controller had to configure these I/O devices.
