ADT7410 Status Register's Tlow and Thigh bits are never set to '!' as expected?

Question I am using the ADT7410's Interrupt mode for INT and CT pins, 13 bits resolution, the ID register is '011' for the revision. The test is : Ambient temperature is 25°C, with trigger of 27°C, and hysteresis of 1°C. The chip is heated. The interrupt pin is working properly regarding the curve in the datasheet Rev A(Figure 19 page 21), there are two pulses, one when the temperature goes higher than the trigger, and the other when the temperature goes lower than the trigger minus the hysteresis. However, when I try to read the Status register to confirm if is the high or the low trigger, I obtain '0' for both. I also try to read the LSB in the temperature with the same results. Is this normal and how can this be fixed? Answer This problem is observed in interrupt mode because the status register is cleared if any register is read after the assertion of T_High, T_low, or T_crit.(see interrupt mode Page 21 of the datasheet.) While in comparator mode the status register bit will remain high until the temperature drops below "T_High – T_Hyst".Therefore, can the customer switch to Comparator mode, which can be enabled by asserting Bit[4] of the configuration register.

Question I am currently trying to implement ADT7410 over I2C in my project. I found AN-1250 on your website. The ZIP-file available for download contains only the header files. I also need ADT7410I2C.c , ADT7410I2C.h and ADT7x10_Demo.c . Please could you send me the missing files? Answer I send you the relevant files including the workspace for IAR ("ADuCM360.eww") - now the project should build successfully. The I2C functions (I2cMWrCfg , I2cTx, I2cFifoFlush, I2cSta, I2cMRdCfg, I2cRx) are part of the I2C library and they are documented in "I2cLib.c" + AN-1159.

NIST traceable calibration certification for ADT7320, ADT7420

Question We are planning to use ADT7410 digital temperature sensor in a temperature tracker design, and our customers require calibration certificates to prove that the sensors are factory calibrated and are traceable to NIST, NPL or PTB. Answer Only ADT7x20 (+/-0.25% accuracy) temperature sensor parts are NIST traceable. This means that the equipment used on its test procedure are calibrated according to NIST standards. Please see the attached NIST statement document. Certificates in the format attached (example for ADT7320) with appendix containing copies of the equipment calibration certificates can be provided.
