general I/O port and the OLVLi bit will not
appear when a match is found but an interrupt
could be generated if the OCIE bit is set.
OCMPi are set while the counter value equals
the OCiR register value (see
64). This behaviour is the same in OPM or
PWM mode.
When the timer clock is f
external clock mode, OCFi and OCMPi are set
while the counter value equals the OCiR regis-
ter value plus 1 (see
for generating external events on the OCMPi
pins even if the input capture mode is also
used.
OLVi bit should be changed after each suc-
cessful comparison in order to control an output
waveform or establish a new elapsed timeout.

Forced Compare Output capability
When the FOLVi bit is set by software, the OLVLi
bit is copied to the OCMPi pin. The OLVi bit has to
be toggled in order to toggle the OCMPi pin when
it is enabled (OCiE bit=1). The OCFi bit is then not
set by hardware, and thus no interrupt request is
generated.
The FOLVLi bits have no effect in both one pulse
mode and PWM mode.

registers are "write only" in Timer A. The corre-
sponding event cannot be generated (OCF2 is
forced by hardware to 0).
