摘要： A microcomputer includes an internal register previously written with an address from an external of the microcomputer. When the address becomes coincident with a register address outputted on an internal register address bus, data on an internal data bus is fetched to a holding register. A content of the holding register is outputted through a serial interface to the external of the microcomputer. Therefore, it is possible to obtain information of an internal resource of the microcomputer which would otherwise not be outputted from the external of the microcomputer, without stopping the execution of the microcomputer even temporarily. Accordingly, a machine controlled by the microcomputer will not run uncontrollably or break down. Furthermore, since the microcomputer is not stopped, it is possible to develop real time information of the actual application.
