Conversion Performances
The analog input pins can be multiplexed with PIO lines. In this case, the assignment of the ADC
input is automatically done as soon as the corresponding channel is enabled by writing the
CHER register . 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.
The ADC is automatically clocked after the first conversion in Normal Mode. In Sleep Mode, the
ADC clock is automatically stopped after each conversion. As the logic is small and the ADC cell
can be put into Sleep Mode, the Power Manager(PM) has no effect on the ADC behavior.
The ADC interrupt line is connected on one of the internal sources of the Interrupt Controller.
Using the ADC interrupt requires the INTC to be programmed first.
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.
For performance and electrical characteristics of the ADC, see the DC Characteristics section.
