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

- 0.5 V). The absolute sum of input overload
currents on all pins may not exceed 50 mA. The supply voltage must remain within the specified limits.
Proper operation is not guaranteed if overload conditions occur on functional pins line XTAL1, RD
, WR, etc.

The timing is valid for pin drivers in high current or dynamic current mode. The reduced static output current in
dynamic current mode must be respected when designing the system.
