Hi,
the output of adxl202 is a PWM signal, tahts mean the duty cycle of the output represent the signal analog value of the signal you can measure

    1- Binary :  the pulse width (Pw) and the period(T0) , then compute then signal value :

        V = K * PW/T0

        where K = The signal amplitude ;

        for that you can use Input Capture mode of Timer1 with multiplexer (2 input to 1 output) to switch          be twine  x and y signak (see CD4053 datasheet)
    2- Analog : you can connect either PWM output  or Xfit and Yfilt with Low pass filter to the ADC Mux inputs of your MCU to measure the signals values using the ADC
