TEMPERATURE, BATTERY, AND SUPPLY VOLTAGE MEASUREMENTS
The ADE7156/ADE7166/ADE7169/ADE7566/ADE7569 include
temperature measurements as well as battery and supply voltage
measurements. (This feature is not available in the ADE7116.)
These measurements enable many forms of compensation. The
temperature and supply voltage measurements can be used to
compensate external circuitry. The RTC can be calibrated over
temperature to ensure that it does not drift. Supply voltage
measurements allow the LCD contrast to be maintained despite

variations in voltage. Battery measurements allow low battery
detection to be performed. All ADC measurements are
configured through the SFRs, as shown in Table 48.
The temperature, battery, and supply voltage measurements can
be configured to continue functioning in PSM1 and PSM2.
Keeping the temperature measurement active ensures that it is
not necessary to wait for the temperature measurement to settle
before using it for compensation.
