Can't Use Motion Detection Interrupt on MPU6050

Hello All,

I am able to use basic feature of MPU6050.

I have also used data ready interrupt but I am unable to use Motion Detection Interrupt.

Here is the sequence of command I have sent but it never trigger motion interrupt.

// Enable INTERRUPT
MPU6050_write_reg(MPU6050_INT_ENABLE, bit(MPU6050_MOT_EN));

// set motion thrashhold
MPU6050_write_reg(MPU6050_MOT_THR, 0x3);

// Clear the 'sleep' bit to start the sensor.
MPU6050_write_reg(MPU6050_PWR_MGMT_1, 0x0);


I have studied document very throughly and understood that need to setup threshold and enable interrupt.

I have done both.

Please suggest what I am missing .

And yes I am using directly oscilloscope to view interrupt signage. So no chance in coding issue in ISR.

Thanks
