One of our customer asked about the interrupt timing of DATA_READY bit and Overrun bit in ADXL346.

If Read Data time spent until after next measurement is started. When is DATA_READY and Overrun interrupt generated?

The following figures is what I said.In the case of DATA_READY interrupt , ① means that DATA_READY bit is set 1 when n+1 data register is updated

② means that DATA _READY is immediately set after data is read. ③ means that Overrun bit is set not to read data.
