Thermostat Setpoints Programming
The thermostat registers (T
OS
and T
HYST
) can be programmed or read via the 2–wire interface. T
OS
is
accessed by setting the DS75 data pointer to the 03h location, and that for the T
HYST
setting is 02h.
The format of the T
OS
and T
HYST
registers is identical to that of the Thermometer register; that is, 12–bit
2’s complement representation of the temperature in
°
C. The user can program the number of bits (9, 10,
11, or 12) for each T
OS
and T
HYST
that correspond to the thermometer resolution mode chosen. If the 9–bit
mode is chosen, for example, the 3 least significant bits of T
OS
and T
HYST
will be ignored by the
thermostat comparator. The format for both T
OS
and T
HYST
is shown below in Table 6. The power–up
default of T
OS
is 80
°
C and that for T
HYST
is 75
°
C.

If the user does not wish to take advantage of the thermostat capabilities of the DS75, the 24 bits can be
used for general storage of system data that need not be maintained following a power loss. The O.S.
output should be left floating if this is done.
