Active-low, push-pull reset output (RST) - STM6718/20/78/80
The RST pin is driven low and stays low whenever V

Active-low, open drain reset output (RST) - STM6717/19/77/79
The RST pin is driven low and stays low whenever V
factory-trimmed or adjustable reset threshold or when MR goes to logic low. It remains low
for t

should be sufficient for most applications.
Push-button reset input (MR)
When MR goes low the RST output is driven low. RST remains low as long as MR is low and
