• PRESCAL: Prescaler Rate Selection (ADC_PRESCAL)
This field defines the conversion clock in function of the Master Clock (MCK):
The ADC clock range is between MCK/2 (PRESCAL = 0) and MCK /128 (PRESCAL = 63). PRESCAL must be pro-
grammed in order to provide an ADC clock frequency according to the parameters given in the AT91M55800A Electrical
Datasheet, literature number 1727.
