2) External circuitry must guarantee low level at the RSTIN
pin at least until both power supply voltages have
reached their operating range.

4) Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin
exceeds the specified range:

< 0). The absolute sum of
input overload currents on all pins may not exceed 50 mA. The supply voltages must remain within the
specified limits.
Proper operation is not guaranteed if overload conditions occur on functional pins such as XTAL1, RD
, WR,
etc.
5) Not subject to production test - verified by design/characterization.
