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.
PWM Event Lines may or may not be used as hardware triggers depending on user
requirements.
The ADC Controller has the FAULT output connected to the FAULT input of PWM. Please refer to
Section 38.6.13 ”Fault Output”
For performance and electrical characteristics of the ADC, see the product DC Characteristics
section.
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
Mode Register” on page 1023
the same register. The ADC Clock frequency is selected in the PRESCAL field of the Mode Reg-
ister (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.
