4.2.3.1 ADC Conversion Timing
Conversion time, t_C = t_ADC × ( 1 + r × (3 + n + STC) ) , where
r = CTC + 2 for CTC = 00_B, 01_B or 10_B,
r = 32 for CTC = 11_B,
CTC = Conversion Time Control (GLOBCTR.CTC),
STC = Sample Time Control (INPCR0.STC),
n = 8 or 10 (for 8-bit and 10-bit conversion respectively),
t_ADC = 1 / f_ADC
