Abstract
PURPOSE:To easily perform the break of a user program including an ordinary interruption processing, by providing another interrupt function other than general interruption, and using a data processor as an emulator. CONSTITUTION:In a case where a microprocessor is used as an incircuit emulator, a signal is supplied to a mode setting terminal MOD. A mode decision circuit decodes the signal, and sets a signal ICE at a high level. According to the above, an AND gate circuit G is opened, and the signal from a break terminal can be inputted. In the development of software using the microprocessor, when the user program advances to an address on which the break is desired to be applied, the fact is detected, and a break terminal BRK is set at the high level. Such break request signal is transmitted to an interruption control circuit via the AND gate circuit G.
