Charge Pump - Unexpected Output

When I enable an output pin in stepconf with "charge pump" i would expect to see a signal on that pin that consists of a square wave at some frequency (20hkz?)

I have a pull up resistor 470 ohms on the pin that I have choosen, and nothing happens. My logic probe shows + on the output (no pulsing), so I surmise that the output is not active.

Is there more to it? I plan to build my own retriggerable monostable but I need a signal to monitor first.

open a terminal and type: man charge_pump

There is the info on the charge pump component.

The frequency is based on the base thread.
