INTEGRATED CIRCUIT, DIAGNOSTIC SYSTEM AND DIAGNOSTIC METHOD
First Claim
1. An integrated circuit that performs radio communication with an external apparatus, the integrated circuit comprising:
- a processing circuit;
a diagnostic circuit configured to perform a diagnosis of the processing circuit according to a plurality of diagnostic items; and
a charging circuit configured to store charge for causing the diagnostic circuit to operate, during a period of performing radio communication,wherein the diagnostic circuit is configured to perform the diagnosis on a first subset of the plurality of diagnostic items by using the charge stored in the charging circuit during a first period of not performing radio communication.
