39.5.3 Analog Inputs
The analog input pins can be multiplexed with PIO lines. In this case, the assignment of the ADC input is automat-
ically done as soon as the corresponding channel is enabled by writing the register ADC_CHER. By default, after
reset, the PIO line is configured as input with its pull-up enabled and the ADC input is connected to the GND.
39.5.4 I/O Lines
The pin ADTRG may be shared with other peripheral functions through the PIO Controller. In this case, the PIO
Controller should be set accordingly to assign the pin ADTRG to the ADC function.
39.5.5 Timer Triggers
Timer Counters may or may not be used as hardware triggers depending on user requirements. Thus, some or all
of the timer counters may be non-connected.
39.5.6 Conversion Performances
For performance and electrical characteristics of the ADC, see the DC Characteristics section.
