The Atmel
?/DIV>
 AT30TS00 contains a 16-bit configuration register allowing the user to set key operational features of
the temperature sensor. The configuration register functions are described in Table 6-5 and Table 6-6.

HYSTENB
Hysteresis Enable
00 = 0癈 Disable hysteresis (default power-on condition)
'01' = 1.5癈 Enable hysteresis
10 = 3.0癈 Enable hysteresis
11 = 6.0癈 Enable hysteresis
The purpose of these bits is to control the hysteresis applied to the alarm trip point boundaries.
The above hysteresis applies to all limits when temperature drops below the user specified alarm
trip points. Please note that hysteresis applies to decreasing temperature only. Once ambient
temperature is above a given threshold, it must drop below the boundary limit minus hysteresis in
order for a comparator   VENT
 
 to be cleared.
For example:   If these bits are set to 01 for 1.5癈 and the Upper Alarm Trip limit is set to
85癈, as temperature rises above 85癈, bit 14 of temperature register will be set
to a 1. Bit 14 will remain set until the ambient temperature drops below the
threshold (85癈) minus the hysteresis value or 83.5癈.
Note:
Hysteresis is also applied to the   VENT
 
pin functionality.
 
When either of the
Crit_Alarm Trip or Alarm Window lock bits is set, this bit cannot be altered until
unlocked

Shutdown Mode
0 = Temperature sensor enabled for continuous conversion (power-on default)
1 = Temperature sensor disabled
In Shutdown mode, the temperature sensor is not active and will not generate interrupts or
update temperature data. The   VENT
 pin is deasserted (not driven).
When either of the Crit_Alarm Trip or Alarm Window lock bits is set, this bit cannot be altered
until unlocked.
