INT BATTERY FUNCTION

The int battery function is called for each A/D conversion, and it controls the ADC registers and PWM according to the measurement requested (see Figure 6). It reads eight measurements from the ADC and calculates the average, which is returned to the calling function.

Figure 6ýHere is the battery function to measure current, charge voltage, temperature, and battery voltage, depending on the termination process.
