The functions required to exercise the control functions of the DS2415 are not accessible until the ROM
function protocol has been satisfied. This protocol is described in the ROM functions flow chart
(Figure 7). The 1-Wire bus master must first provide one of the four ROM function commands. After a
ROM function sequence has been successfully executed, the bus master may then provide one of the
function commands specific to the DS2415 (Figure 5).
