Manufacturer identification information

The TMP451 device allows for the two-wire bus controller to query the device for manufacturer and device IDs to

enable software identification of the device at the particular two-wire bus address. The manufacturer ID is

obtained by reading from pointer address FEh. The TMP451 device reads 55h for the manufacturer code.
