Input frequencies

The input frequency for the timer is selected through the software function
i_APCI1500_InitTimerInputClock (...)
Available frequencies:
111.86 kHz ± 100 ppm,
3.49 kHz ± 100 ppm,
1.747 kHz ± 100 ppm.
IMPORTANT!
The timer component internally operates with half of the input frequency.
