Abstract
In a microcomputer provided with a CPU which processes digital signals under control of program instructions, and a converter which converts between analog and digital signals, the operation of the converter is controlled to improve reliability and increase CPU efficiency. In response to a control output from the CPU a conversion control circuit passes an operation stop signal to the CPU during a limited period of conversion in which, for example, conversion accuracy is significantly influenced by CPU noise generation.
