Read/Write Time Slots
Data communication with the DS2413 takes place in time slots, which carry a single bit each. Write-time slots
transport data from bus master to slave. Read-time slots transfer data from slave to master. Figure 12 illustrates
the definitions of the write- and read-time slots.
All communication begins with the master pulling the data line low. As the voltage on the 1-Wire line falls below the
threshold V
a write-time slot and how long data is valid during a read-time slot.
