Description
Ground
Active LOW reset. RESET
and remains low for at least 140ms after V
Active HIGH reset. RESET is asserted if V
and remains high for at least 140ms after V
threshold.
Manual Reset Input. A logic LOW on MR
active as long as MR
active low input has an internal 20kΩ pull-up resistor. The input should be
left open if not used.
