The ADC has multiple clock sources. Selection is determined by the configuration of
PCC_ADCx[PCS]. The dividers should be configured such that the ADC conversion clock

FTM System clock
The FTM module is clocked by the internal SYS_CLK (the FTM module refers to it as system
clock) which could be up to CPU frequency, but the FTM counter allows to be clocked by three
clock sources:
•
System clock (SYS_CLK) from PCC
•
Internal fixed frequency clock
•
External clocks from pins (TCLK[2:0])
The counter clock source selection is controlled by CLKS bits in FTMn_SC register. The
FTM_CLK is controlled by PCC module and could run up to CPU frequency and provide higher
resolution for the FTM timer.
The fixed frequency clock is a fixed clock driven by RTC_CLK. SIM_LPOCLKS[RTCCLKSEL] is
used to select the RTC_CLK source.
