5.1.6
The upper byte of this register is used to specify the
device identification and the lower byte is used to
specify device revision. The device ID for the
MCP98242 is 0x20 (hex).
The revision begins with 0x00 (hex) for the first release,
with the number being incremented as revised versions
are released.
