MCP9843/98243
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
MCP98243 is 0x21 (hex) and the MCP9843 is 0x00
(hex).
The revision (Lower Byte) begins with 0x00 (hex) for
the first release, with the number being incremented as
revised versions are released. The revision for both
MCP9843 and MCP98243 is 0x01.
