Abstract
A control apparatus including a non-volatile RAM divided into a plurality of memory regions including ROM region and RAM region, CPU capable of executing a plurality of types of access to the non-volatile RAM and a protecting portion intervening between the CPU and the non-volatile RAM. The protecting portion includes a register for storing address information capable of specifying address ranges corresponding to the ROM region and RAM region among the memory regions of the non-volatile RAM, access enabling module for enabling the CPU to write data to the ROM region while an enable signal inputted to the protecting portion externally is active, when the CPU performs a write-access to the ROM region, and initializing module for initializing the address information stored in the register to be predetermined address information as an initial value when the enable signal is deactivated after activating the enable signal.
