result of the conversion is transferred to ADC1RH and ADC1RL upon completion of the conversion
algorithm.
If the bus frequency is less than the f
cannot be guaranteed when short sample is enabled (ADLSMP=0). If the bus frequency is less than 1/11th
of the f
sample is enabled (ADLSMP=1).
The maximum total conversion time for different conditions is summarized in
The maximum total conversion time is determined by the clock source chosen and the divide ratio selected.
The clock source is selectable by the ADICLK bits, and the divide ratio is specified by the ADIV bits. For
example, in 10-bit mode, with the bus clock selected as the input clock source, the input clock divide-by-1
ratio selected, and a bus frequency of 8 MHz, then the conversion time for a single conversion is:
