A/D Converter block is a successive approximation analog-to-digital converter
|
|
with a 12-bit accuracy. Up to eight analog input channels can be selected.
|
|
Conversions can be performed in single or repeat mode. Result of the ADC is
|
|
stored in a 32-bit data register corresponding to each channel.
