Each ADC has its own minimal Startup Time that is programmed through the field STARTUP in
the Mode Register, ADC_MR.
A minimal Tracking Time is necessary for the ADC to guarantee the best converted final value
between two channel selections. This time has to be programmed through the TRACKTIM bit
field in the Mode Register, ADC_MR.
