Channel Select
Command Code
Command Parameter
C3h
Selection Code
Sets the 1-Wire IO channel for subsequent 1-Wire communication
commands.
NOTE:
The selection code read back is different from the
code written. See the table below for the respective values.
Selecting a 1-Wire IO channel other that IO0; randomly selecting one of
the available 1-Wire IO channels.
1-Wire activity must have ended before the DS2482 can process this
command.
Command code and parameter will not be acknowledged if 1WB = 1 at the
time the command code is received and the command will be ignored.
If the selection code is not valid, the selection code will not be
acknowledged and the command will be ignored.
None; the channel selection register is updated on the rising SCL edge of
the selection code acknowledge bit.
