Digital temperature sensor and thermal watchdog
When a set-point register is read, all 16 bits are provided to the bus and must be collected
by the controller to complete the bus operation. However, only the 9 most signicant bits
should be used and the 7 LSB of the LSByte are equal to zero and should be ignored.

7.5  OS output and polarity
The OS output is an open-drain output and its state represents results of the device
watchdog operation as described in
Section
7.1. In order to observe this output state, an
external pull-up resistor is needed. The resistor should be as large as possible, up to
200 k&, to minimize the Temp reading error due to internal heating by the high OS sinking
current.
The OS output active state can be selected as HIGH or LOW by programming bit B2
(OS_POL) of register Conf: setting bit OS_POL to logic 1 selects OS active HIGH and
setting bit B2 to logic 0 sets OS active LOW. At power-up, bit OS_POL is equal to logic 0
and the OS active state is LOW.
7.6  OS comparator and interrupt modes
As described in
Section
7.1, the device OS output responds to the result of the
comparison between register Temp data and the programmed limits, in registers Tos and
Thyst, in different ways depending on the selected OS mode: OS comparator or
OS interrupt. The OS mode is selected by programming bit B1 (OS_COMP_INT) of
register Conf: setting bit OS_COMP_INT to logic 1 selects the OS interrupt mode, and
setting to logic 0 selects the OS comparator mode. At power-up, bit OS_COMP_INT is
equal to logic 0 and the OS comparator is selected.
