A common module clock f
and digital parts of the ADC module:
• f
• f
• f
The internal clock for the analog part f
Therefore, the ADC clock prescaler must be programmed to a value that ensures f
does not exceed 10 MHz. The prescaler ratio is selected by bit field CTC in register
GLOBCTR. A prescaling ratio of 32 can be selected when the maximum performance of
the ADC is not required.
