16-BIT TIMER
(Cont’d)
Notes:
1. After a processor write cycle to the OC
i
HR
reg-
ister, the output compare function is inhibited
until the OC
i
LR
register is also written.
2. If the OC
i
E bit is not set, the OCMP
i
pin is a
general I/O port and the OLVL
i
bit will not
appear when a match is found but an interrupt
could be generated if the OCIE bit is set.
3. When the timer clock is f
CPU
/2, OCF
i
and
OCMP
i
are set while the counter value equals
the OC
i
R register value (see
Figure 8
). This
behaviour is the same in OPM or PWM mode.
When the timer clock is f
CPU
/4, f
CPU
/8 or in
external clock mode, OCF
i
and OCMP
i
are set
while the counter value equals the OC
i
R regis-
ter value plus 1 (see
Figure 9
).
4. The output compare functions can be used both
for generating external events on the OCMP
i
pins even if the input capture mode is also
used.
5. The value in the 16-bit OC
i
R
register and the
OLV
i
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 FOLV
i
bit is set by software, the OLVL
i
bit is copied to the OCMP
i
pin. The OLV
i
bit has to
be toggled in order to toggle the OCMP
i
pin when
it is enabled (OC
i
E bit=1). The OCF
i
bit is then not
set by hardware, and thus no interrupt request is
generated.
FOLVL
i
bits have no effect in either One-Pulse
mode or PWM mode.
