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
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
