1-Wire Bus System

The 1-Wire bus is a system that has a single bus master

and one or more slaves. In all instances the DS28E02 is

a slave device. The bus master is typically a microcon-

troller. The discussion of this bus system is broken

down into three topics: hardware configuration, trans-

action sequence, and 1-Wire signaling (signal types

and timing). The 1-Wire protocol defines bus transac-

tions in terms of the bus state during specific time slots,

which are initiated on the falling edge of sync pulses

from the bus master.
