38.3.5 Modulo (FTMx_MOD)
The Modulo register contains the modulo value for the FTM counter. After the FTM
counter reaches the modulo value, the overflow flag (TOF) becomes set at the next clock,
and the next value of FTM counter depends on the selected counting method; see
Writing to the MOD register latches the value into a buffer. The MOD register is updated
with the value of its write buffer according to
Registers updated from write buffers
If FTMEN = 0, this write coherency mechanism may be manually reset by writing to the
SC register whether BDM is active or not.
Initialize the FTM counter, by writing to CNT, before writing to the MOD register to
avoid confusion about when the first counter overflow will occur.
