5.2.6 AMC7812EVM GPIO + Temp Page
The AMC7812EVM contains one internal local temperature sensor and two temperature measurement
ports, D1 and D2, that are used for sensing temperatures from external remote locations. Figure 28 shows
the GPIO + Temp page.
Figure 28. GPIO + Temp Page
The GPIO + Temp page allows the user to access or observe the AMC7812 registers related to the three
temperature monitoring functions. Pressing the READ TEMP button enables a temperature conversion
and updates the temperature value for all temperature functions in Celsius (°C) and hexadecimal.
Additionally, these functions can be modified by adjusting the corresponding
Hysteresis and nFactor
values.
Figure 29. Temperature Read
The ALARMS page also ties into the functionality of the GPIO + Temp page, as this page determines the
low and high threshold for all temperature configurations. Figure 30 shows where to program the limits by
entering the desired Celsius values into the low or high limit fields.
