发明名称 SINGLE CHIP MICROCOMPUTER
摘要 <p>PURPOSE:To monitor the internal RAM data without interposing a software processing by using a prescribed RAM data output means, and outputting periodically an internal RAM address designated to an exclusive address register to the outside. CONSTITUTION:By setting in advance an internal RAM address to be monitored to address registers 1, 2 from the outside, whenever an access to the internal RAM address set to an internal address bus 201 and an internal data bus 202 of a single chip microcomputer is generated, the latest internal RAM data value is updated automatically, and outputted periodically to the outside. In such a way, the internal RAM data can be monitored without interposing a software processing for spoiling a real time property of a user program.</p>
