 Within each LM75 directory, you can find the following files:
-* temp
+* temp (LM75_SYSCTL_TEMP)
   A list of three numbers. The first number is the Overtemperature Shutdown
-  value, the second number is Overtemperature Shutdown value, and the third
-  number is the current temperature. The first two values can be modified.
-  Each value can be set and read to half-degree accuracy. All values are in
-  degrees Celcius.
+  value, the second number is Hysteris value, and the third number is the
+  current temperature. The first two values can be modified. Each value can
+  be set and read to half-degree accuracy. All values are in degrees Celcius.
   An alarm is issued (usually to a connected LM78) when the temperature 
   gets higher then the Overtemperature Shutdown value; it stays on until
   the temperature falls below the Hysteris value.
-  If read through sysctl, this is a list of longs, each being the temperature
-  times 10.
+  If accessed through sysctl, this is a list of longs, each being the
+  temperature times 10.
+
+The data for each LM75 is updated each 1.5 seconds, but only if it is actually
+read.
