摘要：
A data processor includes a CPU and an A/D converter for converting one of several analog inputs into digital data. A data memory stores data designating analog inputs to be converted. A circuit, responsive to an A/D conversion completion signal from the A/D converter, supplies a macro service operation request to the CPU, which interrupts the CPU without having to save the contents of a CPU program counter and a CPU status register. Upon completion of the A/D conversion, the converted digital data are stored in a predetermined location, and CPU execution resumes.
