9.8.1 FlexTimer module (FTM)

The FlexTimer module is an up to six-channel timer that supports input capture, output
compare, and the generation of PWM signals to control electric motor and power
management applications. FTM time reference is a 16-bit counter that can be used as an
unsigned or signed counter.
This MCU contains up to three FTM modules with one 6-channel FTM and two 2-
channel FTMs. FTM0 and FTM1, each of which has two independent channels, are fully
compatible to the TPM. FTM2, which has six channels, is backward compatible to the
TPM for simple configuration and operation, and features hardware deadtime insertion,
pairs with complementary outputs, generation of triggers, and fault inputs.
Each FTM module has independent external clock input. The following table summarizes
the external signals of FTM modules.
