8.4 THigh_Limit Register (address = 03h) [reset = 5000h]

This register is used to configure the high 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 5000h or 80 °C in normal mode format.

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