Conversion and sample time control
The conversion and sample times are programmed via the bit fields ADCTC and ADSTC
respectively of the register ADCON1. Bit field ADCTC (conversion time control) selects
the internal ADC clock - adc_clk. Bit field ADSTC (sample time control) selects the
sample time.
The total A/D conversion time is given by:
t
