13.1
When the OCM control bits (OCxCON<2:0>) are set to
‘100’, the selected output compare channel initializes
the OCx pin to the low state and generates a single out-
put pulse.
To generate a single output pulse, the following steps
are required (these steps assume the timer source is
initially turned off, but this is not a requirement for the
module operation):
1.
2.

Note:
Determine the instruction clock cycle time. Take
into account the frequency of the external clock
to the timer source (if one is used) and the timer
prescaler settings.
Calculate time to the rising edge of the output
pulse relative to the TMRy start value (0000h).
Calculate the time to the falling edge of the pulse
based on the desired pulse width and the time to
the rising edge of the pulse.
Write the values computed in steps 2 and 3
above into the Compare register, OCxR, and the
Secondary
respectively.
Set Timer Period register, PRy, to value equal to
or greater than value in OCxRS, the Secondary
Compare register.
Set the OCM bits to ‘100’ and the OCTSEL
(OCxCON<3>) bit to the desired timer source.
The OCx pin state will now be driven low.
Set the TON (TyCON<15>) bit to ‘1’, which
enables the compare time base to count.
Upon the first match between TMRy and OCxR,
the OCx pin will be driven high.
When the incrementing timer, TMRy, matches the
Secondary Compare register, OCxRS, the
second and trailing edge (high-to-low) of the pulse
is driven onto the OCx pin. No additional pulses
are driven onto the OCx pin and it remains at low.
As a result of the second compare match event,
the OCxIF interrupt flag bit is set, which will
result in an interrupt if it is enabled, by setting
the OCxIE bit. For further information on periph-
eral interrupts, refer to Section 6.0 “Interrupt
Controller”.
Timer and Compare register settings, if needed,
and then issue a write to set the OCM bits to ‘100’.
Disabling and re-enabling of the timer and clear-
ing the TMRy register are not required, but may
be advantageous for defining a pulse from a
known event time boundary.

The output compare module does not have to be dis-
abled after the falling edge of the output pulse. Another
pulse can be initiated by rewriting the value of the
OCxCON register.

When the OCM control bits (OCxCON<2:0>) are set to
‘101’, the selected output compare channel initializes
the OCx pin to the low state and generates output
pulses on each and every compare match event.
For the user to configure the module for the generation
of a continuous stream of output pulses, the following
steps are required (these steps assume the timer
source is initially turned off, but this is not a requirement
for the module operation):
