7.6.1.14 Manufacturer and Device Identification Plus Revision Registers

The TMP9R00-SP device allows the two-wire bus controller to query the device for manufacturer and device identifications (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 device ID is obtained from register FFh. Note that the most significant byte of the Device ID register identifies the TMP9R00-SP device revision level. The TMP9R00-SP device reads 0x5449 for the manufacturer code and 0x0468 for the device ID code for the first release.
