FlexTimer Module (FTM)
39.1 Chip-specific FTM information

39.1.1 Instantiation Information

This device contains three FlexTimer modules.
The following table shows how these modules are configured. This adheres to Kinetis K
series FTM instantiations.
FTM instance
FTM0
FTM1
FTM3
1. These registers are not available in FTM1: FTM1_C2SC, FTM1_C3SC, FTM1_C4SC, FTM1_C5SC, FTM1_C6SC,
FTM1_C7SC, FTM1_C2V, FTM1_C3V, FTM1_C4V, FTM1_C5V, FTM1_C6V, and FTM1_C7V
CnSC[ICRST] is available only on FTM1, which has Hall
sensor decoder mode. FTM0 and FTM2 do not have this field.

39.1.2 External Clock Options

By default each FTM is clocked by the internal fast peripheral clock (the FTM refers to it
as system clock). Each module contains a register setting that allows the module to be
clocked from an external clock instead. There are three external FTM_CLKINx pins that
can be selected by any FTM module via the SIM_SOPT4 register as an external clock
source. The pinmux options may provide optional external inputs.
