Claims (1)

A/D컨버터가 내장된 MCU에 있어서, 테스트하고저 하는 아나로그 전압 레벨에 해당하는 디지탈값을 A/D테스트 로드 레지스터에 로드하고, A/D테스트 로드 레지스터에 로드된 값에 따라 D/A컨버터를 거쳐 비교기 입력을 발생하고 A/D변환이 종료되면 인터럽트 플래그를 세트하고, 그에 동기되어 A/D결과 레지스터와 A/D테스트 로드 레지스터의 내용의 비교에 의하여 그 비교결과가 A/D테스트 에러 레지스터에 세트되면 상기 A/D테스트 에러 레지스터를 테스트함으로서 A/D변환 검증이 자동적으로 되도록한 것을 특징으로 하는 A/D컨버터 테스트 장치.In MCU with built-in A / D converter, the digital value corresponding to the analog voltage level to be tested is loaded into the A / D test load register, and the D / A according to the value loaded in the A / D test load register. When the comparator input is generated through the converter and the A / D conversion is completed, the interrupt flag is set and the result is compared to the A / D test register by comparing the contents of the A / D result register and the A / D test load register. A / D converter test apparatus characterized in that the A / D conversion verification is automatically performed by testing the A / D test error register when the error register is set. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
