DEVICE ID AND REVISION

There are two Device ID and Revision ID registers.

Address pointer 0x07 is specific to TSE2004av devices

and it is used to identify compliant devices. Address

Pointer 0x08 is a Microchip-specific register and it is

used to identify Microchip devices. The upper byte of

these registers is used to specify the device identifica-

tion and the lower byte is used to specify device silicon

revision. The device ID for the MCP98244 is 0x22 (hex)

(same as TSE2004av).

The revision (Lower Byte) begins with 0x00 (hex) for

the first release, with the number being incremented as

revised versions are released.
