6.7.    Temperature Register (16-bit Read only, Address = 05h)
The temperature register holds the internal temperature measurement data represented in 11-bit 2s complement
word format allowing for resolution equal to 0.125癈 (least significant bit). The upper three bits (15, 14, 13) of the
temperature register indicates the trip status of the current temperature and most important, are not affected by
the status of the output of the   VENT
 pin (see Table 6-13 and Table 6-14).

Description
15
CRITHIGH     0 = Ambient temperature is less than the Critical Alarm Trip Register setting
1 = Ambient temperature is greater than or equal to Critical Alarm Trip Register setting
When this bit is set 1, it will automatically clear once the measured temperature decreases
below or is equal to the trip point minus any hysteresis set
14
ALMHIGH
0 = Ambient temperature is below the Upper Alarm Trip register setting
1 = Ambient temperature is above the Upper Alarm Trip register setting
When the bit is set 1, it will automatically clear once the measured temperature decreases
below or is equal to the trip point minus any hysteresis set
13
ALMLOW
0 = Ambient temperature is above the Lower Alarm Trip register setting
1 = Ambient temperature is below the Lower Alarm Trip register setting
When the bit is set 1, it will automatically clear once the measured temperature increases
above or is to equal to the trip point
