8.3 TLow_Limit Register (address = 02h) [reset = 4B00h]

This register is used to configure the low temperature alert limit of the TMP110. The limit is formatted in a 12-bit or 13-bit two's complement format with a LSB equal to 62.5 m°C depending on the Extended_Mode bit setting in the configuration register. The default value on start-up is 4B00h or 75 °C in normal mode format.

Note: If the temperature register format is changed, the low limit register value must be updated accordingly.
