. The initiation and removal of the NMI signal during
power-up results in an NMI pulse of from 0
μ
s minimum
to 500
μ
s maximum, depending on the relative voltage
relationship between V
CC
and the IN pin voltage. As an
example, when the IN pin is tied to ground during pow-
er-up, the internal time-out will result in a pulse of 200
μ
s
minimum to 500
μ
s maximum. In contrast, if the IN pin is
tied to V
CCO
during power-up, NMI will not produce a
pulse on power-up. Note that a fast slewing power sup-
ply may cause the NMI to be virtually non-existent on
power-up. This is of no consequence, however, since a
RST will be active.
