    Did not understand the part regarding pin 13 self test. How does the self test work again and what do you have to apply to pin 13 to initiate a self test? Thanks

      A logic high to pin 13 will initiate the self test feature. Turn the MMA7361 upside down to create a -1G output on the Z axis. Applying a high to pin 13 will cause a +1G output. This verifies the mechanical and electronic sections of the MMA7361.
      A electrostatic charge is applied to the axis to simulate g forces.

    what is the purpose of a decouple between VCC and ground?

    I want to know that when actually sesnor responds for free fall ? That is in air or after cooking to ground ?

      In the air while falling with only gravity acting on the sensor.

    Sir , at gselect port only discrete ranges are applied or we can apply any range that we want. Thanks : )

    • @0033mer

      Only two discrete ranges can be selected. +/- 1.5 and +/- 6 g.

      Generally speaking people out here will not do homework. When you do ask a question be very specific then someone may answer. ie
      " i get the circuit diagram ? " This may mean something to you but no one out here has a clue.
