|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the
|
|
.Tn National Semiconductor
|
|
LM on iicbus series temperatures and register compatible chips to be used
|
|
with the
|
|
.Xr envsys 4
|
|
API.
|
|
The
|
|
.Nm
|
|
supports ranges of the temperature between +125 from -55.
|
|
.Pp
|
|
Each device is specified by the value of the address and flags.
