Description
6/29
The STM65xx devices have active-low (optionally active-high) open-drain reset (RST)
output(s) with or without internal pull-up resistor or push-pull as output options, with factory-
programmed or capacitor-adjustable or push-buttons defined output reset pulse duration,
with or without power-on reset function.
Some devices also have an undervoltage monitoring feature: the reset output is also
asserted when the monitored supply voltage V
reset output remains asserted for the reset timeout period (t
voltage goes above the specified threshold.
