42.5.6 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 unconnected.
42.5.7 PWM Event Line
PWM Event Lines may or may not be used as hardware triggers depending on user requirements.
42.5.8 Fault Output
The ADC Controller has the FAULT output connected to the FAULT input of PWM. Please refer to
and implementation of the PWM in the product.
42.5.9 Conversion Performances
For performance and electrical characteristics of the ADC, see the product electrical characteristics.

Functional Description
42.6.1 Analog-to-Digital Conversion
The ADC uses the ADC Clock to perform conversions. Converting a single analog value to a 12-bit digital data 
requires Tracking Clock cycles as defined in the field TRACKTIM of the 
. The ADC Clock 
frequency is selected in the PRESCAL field of the Mode Register (ADC_MR). The tracking phase starts during the 
conversion of the previous channel. If the tracking time is longer than the conversion time, the tracking phase is 
extended to the end of the previous conversion.
The ADC clock range is between MCK/2, if PRESCAL is 0, and MCK/512, if PRESCAL is set to 255 (0xFF). 
PRESCAL must be programmed in order to provide an ADC clock frequency according to the parameters given in 
the product “Electrical Characteristics” section.
