RST/
RST1
Active-Low Reset Output,
Open-Drain or Push-Pull.
RST/RST1 changes from
high to low when V
CC1
or V
CC2
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
CC1
/V
CC2
/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
CC1
.
