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
output pulse.
To generate a single output pulse, the following steps
are required. These steps assume timer source is
initially turned off though this is not a requirement for
the module operation.
1. Determine the instruction clock cycle time. Take
2. Calculate time to the rising edge of the output
3. Calculate the time to the falling edge of the pulse
4. Write the value computed in step 2 into the Output
5. Set Timer Period register, PRy, to a value equal to

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.
To configure the module to generate a continuous
stream of output pulses, the following steps are
required. These steps assume that the timer source is
initially turned off but this is not a requirement for the
module operation.
1. Determine the instruction clock cycle time. Take

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