Generates eight read-data time slots on the 1-Wire line and stores result in the Read Data
Register.
To read data from the 1-Wire line. Equivalent to executing eight 1-Wire Single Bit commands with
V = 1 (write-one time slot), but faster due to less I
1-Wire activity must have ended before the DS2482-100 can process this command.
Command code is not acknowledged if 1WB = 1 at the time the command code is received and
the command is ignored.

acknowledge bit.
Begins maximum 262.5ns after the falling SCL edge of the command code acknowledge bit.
Status Register (for busy polling). Note: To read the data byte received from the 1-Wire line, issue
the Set Read Pointer command and select the Read Data Register. Then access the DS2482-100
in read mode.
1WB (set to 1 for 8 x t

A5h
Data Byte
Writes a single data byte to the 1-Wire line.
To write commands or data to the 1-Wire line. Equivalent to executing eight 1-Wire Single Bit
commands, but faster due to less I
1-Wire activity must have ended before the DS2482-100 can process this command.
Command code and data byte are not acknowledged if 1WB = 1 at the time the command code is
received and the command is ignored.
8 x t
Begins maximum 262.5ns after falling SCL edge of the LSB of the data byte (i.e., before the data
byte acknowledge). Note: The bit order on the I
first; I
the full data byte.
Status Register (for busy polling).
1WB (set to 1 for 8 x t
1WS, SPU, APU apply.
