PHANTOM CLOCK REGISTER DEFINITION Figure 1
DS1251/DS1251P
Note: The pattern recognition in Hex is C5, 3A, A3, 5C, C5, 3A, A3, 5C. The odds of this pattern being
accidentally duplicated and causing inadvertent entry to the phantom clock is less than 1 in 10¹⁹. This
pattern is sent to the phantom clock LSB to MSB.
