Automatic Power-Down
Single-Shot Conversion
Figure 83. Analog-to-Digital Converter Block Diagram
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.
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:
