(T-HIGH) and the point at which you desire the W7100 to
be fully reset (T-LOW). At the intersection of the two
points is the value of the resistor to be placed in series (R

)
and the value of the resistor to be placed in parallel (R
P
).
Indicated resistor values are standard resistors and can be
purchased locally.
