Operation  
Automatic Power-Down  
If the ADC is idle (no conversions in progress) for 160 consecutive system clock cycles,  
portions of the ADC are automatically powered-down. From this power-down state, the  
ADC requires 40 system clock cycles to power-up. The ADC powers up when a conver-  
sion is requested using the ADC Control register.  
Single-Shot Conversion  
When configured for single-shot conversion, the ADC performs a single analog-to-digital  
conversion on the selected analog input channel. After completion of the conversion, the  
ADC shuts down. The steps for setting up the ADC and initiating a single-shot conversion  
are as follows:
