RST/
RST1
Active-Low Reset Output,
Open-Drain or Push-Pull.
RST/RST1 changes from
high to low when V
CC
1 or
V
CC
2 drops below the
selected reset thresholds,
RSTIN is below threshold,
MR is pulled low, or the
watchdog triggers a
reset. RST/RST1 remains
low for the reset timeout
period after V
CC
1/
V
CC
2/RSTIN exceed the
device reset thresholds,
MR goes low to high, or
the watchdog triggers a
reset. Open-drain outputs
require an external pullup
resistor. Push-pull
outputs are referenced to
V
