Abstract
The microcomputer provides with surroundings where data in a RAM can be monitored on the outside without employing an external bus. When a command requesting accessing to a RAM is received from an external monitor, a real time debugger built in the microcomputer confirms that a CPU is not accessing the RAM, and accesses the RAM. On the other hand, when accessing to an emROM, which emulates an actual ROM, is requested from the monitor, the real time debugger accesses one of emROMs which is not being used by the CPU at present.
