The Temperature Data Register holds the 10-bit + sign data for the internal temperature measurement as well as the status bits indicating which
Bit 15 – TCRIT; When set, the temperature is above the TCRIT Limit. This bit will remain set so long as the temperature is above TCRIT and will
Bit 14 – HIGH; When set, the temperature is above the High Limit. This bit will remain set so long as the temperature is above the HIGH limit. Once
Bit 13 – LOW; When set, the temperature is below the Low Limit. This bit will remain set so long as the temperature is below the Low Limit minus
This register allows the user to change the resolution of the temperature sensor. The POR default resolution is 0.25°C. The resolution imple-

The Manufacturer ID Register holds the PCI SIG number assigned to the specific manufacturer.
The upper byte of the Device ID / Revision Register stores a unique number indicating the TS3000B3A from other devices.
The lower byte holds the revision value.
Resolution defined based on value of TRES field of the Capabilities Register. Unused/unsupported bits will read as 0.
