FlexTimer Module (FTM)

19.1 Chip specific FlexTimer module

This device has one Flextimer (FTM) module.
The FlexTimer module is a two-channel timer that supports input capture, output
compare, and the generation of PWM signals. FTM time reference is a 16-bit counter that
can be used as an unsigned or signed counter. It is fully backward compatible to the
TPM.
FTM module has independent external clock input. The following table summarizes the
signals of FTM module.
Customization:
• Primary clock: BUSCLK (20 MHz)
• Alternate clock: ICSFFCLK/2, TCLK
• FTM module has independent external clock input. The following table summarizes
thel signals of FTM module.
