It is deasserted if it sees you have a 1A charger in there, has been for
a while.
A related question: I presume that it is the electrical signal
EN_USBHOST which flips the switch which causes the USB port to source
current in host mode, as opposed to sinking current in device mode.
This is of course what is expected of a USB host, but it also prevents
us from charging the Freerunner when the USB port is in host mode, if an
appropriate power source is available.
Question:
Is it possible to charge the Neo Freerunner when using the USB port in
host mode, by ascerting LOGICAL hostmode and by NOT asserting EN_USBHOST?
