32 / 50 page  Table 8-8. Alert_Status Register Field Descriptions (continued) Bit Field Type Reset Description 2 THigh_Flag RC 0h High temperature flag indicator. This indicates that the latest temperature conversion has cross above the THigh_Limit register threshold or crossed below the THigh_Limit - THigh_Hyst threshold. Reading Alert_Status register will clear this bit. 0h = The most recent temperature conversion has not crossed the THigh_Limit or the hysteresis threshold. 1h: A temperature conversion crossed the THigh_Limit or crossed below the THigh_Limit - THigh_Hyst threshold. Once the THigh_Flag is set, THigh_Flag will not be set again until a temperature conversion is below THigh_Limit - THigh_Hyst 1 TLow_Flag RC 0h Low temperature flag indicator. This indicates that the latest temperature conversion has cross below the TLow_Limit register threshold or crossed above the Tlow_Limit + TLow_Hyst threshold. Reading Alert_Status register will clear this bit. 0h = The most recent temperature conversion has not crossed the TLow_Limit or the hysteresis threshold. 1h: A temperature conversion crossed below the TLow_Limit. Once the TLow_Flag is set, TLow_Flag will not be set again until temperature conversion is above TLow_Limit + TLow_Hyst 0 Data_Ready_Flag RC 0h Data Ready flag indicator. This indicates a new temperature conversion result is available. This bit is only cleared by reading the Alert_Status register . 0h = Data_Ready_Flag has been cleared since the last temperature conversion 1h = Data in Temp_Result is new 8.6.4 Configuration Register (Address = 03h) [reset = 0004h] This register is used to configuration the operation of the TMP114.

Configuration Register Field Descriptions Bit Field Type Reset Description 15:8 Reserved R 00h Reserved 10:9 ADC_Conv_Time[1:0] R/W 0h ADC Conversion Time setting. This bit field changes the ADC conversion time and resolution of the TMP114. If the averaging time is longer than the conversion period setting the minimum cycle time will be the averaging time. 0h = 6.4 ms 1h = 3.5 ms 2h = 2.0 ms 3h = 1.2 ms TMP114 SNIS214A – JUNE 2021 – REVISED SEPTEMBER 2021 www.ti.com 32 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: TMP114 |
