DISTRIBUTED SYSTEM INTERFACE (DSI) SENSOR INTERFACE

Motorola => Freescale 

Freescale Semiconductor, Inc.

Programmable address devices all power up with a device

address of $0 in their address register and their bus switches

open. In the daisy chain, if the first device receives the

initialization command device on BUSIN, it will accept the

address in the command and close its switch at the end of the

command. The next device in the chain will now be able to

receive the initialization command on its BUSIN and will accept

the next address. This proceeds down the chain until the last

device is addressed. The devices can also be initialized by the

reverse initialization command if the signal is applied to

BUSOUT.

Pre-programmed devices power up with their pre-

programmed address in its address register. It will ignore all

Initialization commands unless the address in the command

matches its pre-programmed address. In this event the device

stores the other information contained in the Initialization

command.
