Active-Low Open-Drain or Push-Pull Reset Output. RESET changes from high
to low when V
threshold, MR is pulled low, or the watchdog triggers a reset. RESET remains
low for the reset timeout period after all voltages exceed the device reset
threshold, MR goes low to high, or the watchdog triggers a reset.
Active-High Push-Pull Reset Output. RESET changes from low to high when
V
is pulled low, or the watchdog triggers a reset. RESET remains HIGH for the
reset timeout period after all voltages exceed the device reset threshold, MR
goes low to high, or the watchdog triggers a reset.
