RESET is asserted LOW if VCC falls below the reset threshold and remains LOW for the

240ms typical reset timeout period (140ms minimum) after VCC exceeds the threshold.

RESET is asserted HIGH if VCC falls below the reset threshold and remains HIGH for the

240ms typical reset timeout period (140ms minimum) after VCC exceeds the threshold.
