PRELIMINARY
Read/Write Time Slots
The definitions of write and read time slots are illustrated in Figure 11. The master initiates all time slots
by driving the data line low. The falling edge of the data line synchronizes the DS2432 to the master by
triggering an internal delay circuit. During write time slots, the delay circuit determines when the DS2432
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 DS2432 will hold the data line low. If the data bit is a “1”, the DS2432 will not
hold the data line low at all.
