A reset cable can be connected directly to a "PC
reset header". The watchdog uses a static switch
with an ON resistance of about 35 ohms. The
polarity at the switch input doesn't matter.
In the drawing is illustrated the control of PC reset
by button or by the Picolo Tetra. The switch can
also be used for other purposes than resetting the
computer: for example, it can activate an alarm.
The two "PC reset headers" are equivalent.
See also topic "Using the watchdog" in the electronic documentation.
