affects only the Temperature Data Register but none of the Limit Registers. When higher resolution devices generate status or EVENT changes, only
bits B12 through B2 are used in the comparison; however, all 11 bits (TRES[1-0] = 10) or all 12 bits (TRES[1-0] = 11) are visible in reads from the
Temperature Data Register.

The TRES field of the Capabilities Register optionally defines higher resolution devices. For compatibility and simplicity, this additional resolution
When a lower resolution device is indicated in the Capabilities Register (TRES[1-0] = 00), the finest resolution supported is 0.5°C. When this is
The temperature limit registers (High, Low, and TCRIT) define the temperatures to be used by various on-chip comparators to determine device
The High Limit Register holds the High Limit for the nominal operating window. When the temperature rises above the High Limit, or drops below or
The Low Limit Register holds the lower limit for the nominal operating window. When the temperature drops below the Low Limit or rises up to meet
The TCRIT Limit Register holds the TCRIT Limit. If the temperature exceeds the limit, the EVENT pin will be asserted. It will remain asserted until
