Signal
type
Up to 32 external trigger inputs for the regular conversions (can
be connected to on-chip timers).
Inputs
These inputs are shared between the ADC master and the ADC
slave.
Up to 31 external trigger inputs for the injected conversions (can
be connected to on-chip timers).
Inputs
These inputs are shared between the ADC master and the ADC
slave.
