Added references to Application Note 192.
Clarification in the second paragraph of the Device Operation section.
Removed references to DOS from the search accelerator introduction.
Appended to EC table note 16: The DS2480B requires a 1-Wire reset command
sent by the host at a data rate of 9600bps for calibration. Data rates of
115200bps or higher during calibration may put the DS2480B in an undefined
state, requiring a power-down reset to restore normal operation.
