A processing apparatus capable of feeding voltage necessary when writing data in a programmable nonvolatile memory without increasing the number of terminals is presented. A control signal MO for changing over the actual operation mode and test mode, and a program voltage VPP necessary when writing or erasing data in an EEPROM are provided.

Processing apparatus having a nonvolatile memory to which a supply

A computer peripheral device incorporating a multi-task control device which is extremely useful for such programs controlling the microcomputer system. In particular, the multi-task control device effectively controls a plurality of tasks executed by the CPU by using means other than the CPU including such means for controlling operations needed for comparing priority orders between a plurality of tasks, and the other means for generating interrupt operations from this control device against the CPU needed for switching tasks being executed in accordance with the result of the priority comparative operations.
