computer which does not require high voltage for entry

•

In-system programming

•

System protection features:

–

Optional computer operating properly (COP) reset

–

Low-voltage detection with optional reset and selectable trip

points for 3.0 V and 5.0 V operation

–

Illegal opcode detection with reset

–

Illegal address detection with reset

•

Low-power design; fully static with stop and wait modes

•

Standard low-power modes of operation:

–

Wait mode

–

Stop mode
