    You need just to invert instruction order:

        PD_DDR = 0x2D;                  \* PD7 input       *\

        PD_CR1 = 0x2D;                   \* PD7 floating   *\

        EXTI_CR1 = 0x48;               

        EXTI_CR2 = 0x06;                \* set rising edge on TLI *\

        PD_CR2 = 0x80;                    \* PD7 interrupt *\

    It is reported in the RM:

    TLIS: Top level interrupt sensitivity

    This bit is set and cleared by software. This bit can be written only when the external interrupt is disabled on the corresponding GPIO port (PD7).

    0: Falling edge.

    1: Rising edge Regards,

      Olga
