Overview
The ATmega8HVA/16HVA features a 12-bit Sigma-Delta ADC.
The Voltage ADC (V-ADC) is connected to five different sources through the Input Multiplexer.
There are two differential channels for Cell Voltage measurements. These channels are scaled
0.2x to comply with the Full Scale range of the V-ADC. In addition there are three single ended
channels referenced to SGND. One channel is for measuring the internal temperature sensor
VPTAT and two channels for measuring the voltage at ADC0 and ADC1.
When the V-ADC is not used, power consumption can be minimized by writing the PRVADC bit
in PRR0 to one. See 鈥漃RR0 鈥� Power Reduction Register 0鈥� on page 39 for details on how to use
the PRVADC bit.

Operation
To enable V-ADC conversions, the V-ADC Enable bit, VADEN, in V-ADC Control and Status
Register 鈥� VADCSR must be set. If this bit is cleared, the V-ADC will be switched off, and any
ongoing conversions will be terminated. The V-ADC is automatically disabled in Power-save and
