42.6.10 ADC Timings
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
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 field in the ADC_MR.
