A CPU 11 counts oscillating pulses of the CR oscillating circuit 21 in a predetermined time measured by a time counter 25 in response to a clock signal of a main clock 13 by a crystal oscillator, and corrects the target count Pm according to a pulse count P thereof. Since the real count state is obtained based upon the clock signal of the main clock having high frequency accuracy without the estimation of the sub clock 20, the high accuracy of the sub clock is retained even if environmental changes such as temperatures occur."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Microcomputer and method for correcting clock thereof","description":"ProblemA sub clock for a sleep mode in a a microcomputer is retained to be operable with high accuracy.SolutionA sub clock 20 counts oscillating pulses of a CR oscillating circuit 21 by a loop counter","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9817432","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
