Patent ID: 11921910
Assignee: STMICROELECTRONICS S.R.L.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 13:
14. An electronic circuit comprising:
a first input terminal configured to receive a command field;
a second input terminal configured to receive a parameter field;
a first output terminal configured to deliver a service handler address indicative of a start address of a service handler of a set of service handlers;
a parameter check circuit configured to generate a first error signal indicative of whether the parameter field is valid; and
a message handler circuit configured to:
receive a handler number indicative of a number of service handlers in the set of service handlers,
receive a look-up-table (LUT) start address indicative of a start address of a LUT,
receive a second error signal indicative of whether there is an error associated with the command field, wherein the second error signal is based on the first error signal,
determine the service handler address based on the handler number, the LUT start address, and the second error signal, and
deliver the service handler address to the first output terminal.
