Reset output (Push Pull), active low
H = VDD > VTRIP, Reset pin is inactive
(after Reset Timer Delay completes)
L = VDD < VTRIP, Reset pin is active
Goes active (Low) if one of these conditions
occurs:
1.
If VDD falls below the selected Reset
voltage threshold.
2.
If the MR pin is forced low.
3.
During power-up.
