3.
Then, on a valid event on the ICAP1 pin, the counter is initialized to FFFCh and OLVL2 bit is
loaded on the OCMP1 pin, the ICF1 bit is set and the value FFFDh is loaded in the IC1R
register.
Because the ICF1 bit is set when an active edge occurs, an interrupt can be generated if the
ICIE bit is set.
Clearing the Input Capture interrupt request (that is, clearing the ICFi bit) is done in two
steps:
1.
2.
The OC1R register value required for a specific timing application can be calculated using
the following formula:
Where:
t
f
PRESC
If the timer clock is an external clock the formula is:
Where:
t
f
When the value of the counter is equal to the value of the contents of the OC1R register, the
OLVL1 bit is output on the OCMP1 pin, (See

Set the OC1E bit, the OCMP1 pin is then dedicated to the Output Compare 1
function.
