That nicely describes the "auto-start" PNC, which is elegently simple in
my opinion, because with one each of an inverter, capacitor, resistor,
and diode you kill all the processes except one.
The PNC I was attempting to describe (poorly) is the one in which the
inverter input is grounded until all the processes have been absorbed
(consumed, deleted). This leaving you with an inactive microcore unless
you manage to "turn off" the PNC just before it deletes the last
circulating process.
Both versions work by preventing a neuron from passing on a process for
a specified time.
