ON/OFF
Digital input
Typically connected to an ON/OFF
push button. Boots device in
response to a button press when
power is still present from battery
and/or charger but software has
placed the device in the OFF or
DORMANT state. Additionally
useable as a digital input in normal
operation. No pull.
