Abstract

Communicating with verified data includes receiving a request with a first device where the request is addressed to a register within the first device and sending a response with the first device to a second device where the response includes an address of the register.

Claims

1. A method for communicating with verified data, comprising:

receiving a request with a first device, said request addressed to a register within said first device; and

sending a response with said first device to a second device, said response comprising an address of said register.

2. The method of claim 1, further comprising receiving a chip select signal prior to receiving said request.

3. The method of claim 1, wherein receiving a request with a first device addressed to a register within said first device includes said request comprising a first byte comprising a command and a second byte comprising said address of said register.

4. The method of claim 3, wherein said command is a read command.

5. The method of claim 3, wherein said command is a write command.

6. The method of claim 1, wherein said response further comprises data requested in said request and a checksum to protect said data.

7. A computer program product, comprising:

a tangible computer readable storage medium, said computer readable storage medium comprising computer readable program code embodied therewith, said computer readable program code comprising;

computer readable program code to send a request for data to a register; and

computer readable program code to receive a response to said request, said response comprising an address of said register and said data with a checksum.

8. The computer program product of claim 7, further comprising computer readable program code to compare said address in said response to said register in said request upon receipt of said response.

9. The computer program product of claim 8, further comprising computer readable program code to resend said request when said address in said response fails to match said register in said request.

10. The computer program product of claim 7, further comprising computer readable program code to evaluate said checksum to determine whether said data is corrupted.

11. A system for communicating with verified data, comprising:

a processor programmed to

send a request to a register over a bus for data;

receive a response comprising an address of said register and said data; and

compare said address in said response to said address upon receipt of said response.

12. The system of claim 11, wherein said processor is further programmed to evaluate a checksum sent with said data upon receipt of said response.

13. The system of claim 12, wherein said processor is further programmed to resend said request when said checksum indicates that said data is corrupted.

14. The system of claim 11, wherein said processor is further programmed to resend said request when said address in said response fails to match said register.

15. The system of claim 11, wherein said processor is incorporated in a power meter.
