1-WIRE BUS SYSTEM
The DS2434 1-Wire bus is a system which has a single bus master and one slave. The DS2434 behaves as
a slave. The DS2434 is not able to be multidropped, unlike other 1-Wire devices from Dallas
Semiconductor.
The discussion of this bus system is broken down into three topics: hardware configuration, transaction
sequence, and 1-Wire signaling (signal types and timing).
