void TAC_TachoTimerInit(void)
The purpose of this function is to initialize the timer that will perform the
tacho signal period measurement (the timer can be chosen in the
75x_tacho_prm.h file). The peripheral clock and the capture interrupt
are enabled, and the timer is initialized in “clear on capture” mode.

The timer starts counting at the end of the routine.
