RESET is asserted
LOW if VCC falls below
VTH and remains LOW
for TRST after VCC
exceeds the threshold.

MR
Manual Reset Input. A
logic LOW on MR
asserts reset. Reset
remains active as long
as MR is LOW and for
TMRST after MR returns
HIGH. The active low
input has an internal
20k. pull-up resistor.
The input should be left
open if not used. It can
be driven by TTL or
CMOS logic or
shorted to ground by a
switch.

RESETIN
Auxiliary Reset input.
Reset asserts when
either VCC or RESET IN
falls below its threshold
voltage.
