15Description
16-----------
17
18The Maixm/Dallas Semiconductor DS2482 is a I2C device that provides
19one (DS2482-100) or eight (DS2482-800) 1-wire busses.

22General Remarks
23---------------
24
25Valid addresses are 0x18, 0x19, 0x1a, and 0x1b.
26However, the device cannot be detected without writing to the i2c bus, so no
27detection is done.
28You should force the device address.
