ADC Clocking Scheme
A common module clock fADC generates the various clock signals used by the analog
and digital parts of the ADC module:
fADCA is input clock for the analog part.
fADCI is internal clock for the analog part (defines the time base for conversion length
and the sample time). This clock is generated internally in the analog part, based on
the input clock fADCA to generate a correct duty cycle for the analog components.
fADCD is input clock for the digital part.
The internal clock for the analog part fADCI is limited to a maximum frequency of 10 MHz.
Therefore, the ADC clock prescaler must be programmed to a value that ensures fADCI
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.
