DS2482-800: Eight-Channel 1-Wire Master
10 of 22
Set Read Pointer
Command Code
Command Parameter
E1h
Pointer Code
Sets the read pointer to the specified register. Overwrites the read pointer
position of any 1-Wire communication command in progress.
To prepare reading the result from a 1-Wire Byte command; random read
access of registers.
None (can be executed at any time)
If the pointer code is not valid, the pointer code will not be acknowledged
and the command will be ignored.
None; the read pointer is updated on the rising SCL edge of the pointer
code acknowledge bit.

D2h
Configuration Byte
Writes a new configuration byte. The new settings take effect immediately.
NOTE:
When writing to the Configuration Register, the new data is
accepted only if the upper nibble (bits 7 to 4) is the one's complement of
the lower nibble (bits 3 to 0). When read, the upper nibble is always 0h.
Defining the features for subsequent 1-Wire communication.
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.
None; the configuration register is updated on the rising SCL edge of the
configuration byte acknowledge bit.
None
Configuration Register (to verify write)
RST set to 0
1WS, SPU, PPM, APU updated
