READ/WRITE TIME SLOTS
The definitions of write and read time slots are illustrated in Figure 11. The master driving the data line
low initiates all time slots. The falling edge of the data line synchronizes the DS199_ to the master by
triggering a delay circuit in the DS199_. During write time slots, the delay circuit determines when the
DS199_ samples the data line. For a read data time slot, if a 0 is to be transmitted, the delay circuit
determines how long the DS199_ holds the data line low overriding the 1 generated by the master. If the
data bit is a 1, the iButton leaves the read data time slot unchanged.
