Figure 40. Pulse width modulation cycle
If OLVL1 = 1 and OLVL2 = 0 the length of the positive pulse is the difference between the
OC2R and OC1R registers.
If OLVL1 = OLVL2 a continuous signal will be seen on the OCMP1 pin.
The OC

Where:
t = Signal or pulse period (in seconds)

If the timer clock is an external clock the formula is:
Where:
t = Signal or pulse period (in seconds)
f
The output Compare 2 event causes the counter to be initialized to FFFCh (See
After a write instruction to the OCiHR register, the output compare function is inhibited until
the OCiLR register is also written.
The OCF1 and OCF2 bits cannot be set by hardware in PWM mode therefore the output
Compare interrupt is inhibited.
The ICF1 bit is set by hardware when the counter reaches the OC2R value and can produce
a timer interrupt if the ICIE bit is set and the I bit is cleared.
In PWM mode the ICAP1 pin can not be used to perform input capture because it is
disconnected to the timer. The ICAP2 pin can be used to perform input capture (ICF2 can be
set and IC2R can be loaded) but the user must take care that the counter is reset each
period and ICF1 can also generates interrupt if ICIE is set.
When the Pulse Width Modulation (PWM) and One Pulse mode (OPM) bits are both set, the
PWM mode is the only active one.
