Function Descriptions
EXAMPLE:
The following C program shows the use of the TIMER8 functions.
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 10KHz frequency
and with 33% Duty cycle at the OCMP1 pin if _Enable_PWM_ is defined in main.c or it gen-
erates the 0.1ms pulse at OCMP1 pin, if _Enable_OPM_ is defined in main.c (Fcpu = 8 MHz).
