INITIALIZATION PROCEDURE “RESET AND PRESENCE PLUSES” Figure 10
*IN ORDER NOT TO MASK INTERRUPT SIGNALING BY OTHER DEVICES ON THE 1-WIRE BUS, tRSTL + tR
SHOULD ALWAYS BE LESS THAN 960 μs
**INCLUDES RECOVERY TIME
READ/WRITE TIME SLOTS
The definitions of write and read time slots are illustrated in Figure 11. All time slots are initiated by the
master driving the data line low. The falling edge of the data line synchronizes the DS2450 to the master
by triggering a delay circuit in the DS2450. During write time slots, the delay circuit determines when
the DS2450 will sample the data line. For a read data time slot, if a “0” is to be transmitted, the delay
circuit determines how long the DS2450 will hold the data line low overriding the 1 generated by the
master. If the data bit is a “1”, the device will leave the read data time slot unchanged.
