EXAMPLE:
The following C program shows the use of the TIMERx functions. Here, x=A as TIMERA is
used. You must define TIMERA in ST7lib_config.h.
Program description:
It compares the output compare2 register value with the free running counter, checks the oc-
currence of (event) leading edge at ICAP2 pin. It generates PWM signal with a frequency of
10KHz and a Duty cycle of 33% on the OCMP1 pin, if _Enable_PWM_ is defined in
ST7lib_confi.h or it generates a 5ms pulse at OCMP1 pin, if _Enable_OPM_ is defined in
ST7lib_config.h (Fcpu = 8 MHz).
