Hi everyone, Im working with the FreeScale's FXTH87xx in a TPMS project. But i cant make the Low Frecuency activate the chip through interruption, im trying to do the simples activation through carrier detection. i follow the datasheet and the TPMS_FXTH87_LF_RF_communitacion example with no luck!!! please i need a guide line to make the LFR work!.

I used the Inductor 7.2mH 105Ohm 3% AEC-Q200  Part N. TPL802727-722H as the LF input 

Thanks for any help!!
