Outputs
Four of the module's twelve outputs are high speed outputs. These outputs can be
configured as high speed counter, PWM, or pulse train outputs.

Counter Outputs

Each counter output has a preset on and off point that must lie between the counter's high
and low limits. The output state indicates when the Accumulator value is between the
Preset on and off points. For example, using the Type B counter:
If the output is enabled for the HSC channel being used, the output turns on as shown in
the following table:
Preset closest to
low limit
ON
OFF
The output can be either on or off when the Accumulator value lies between the Preset
points.
