Q1:Is this time time until register setting is accepted after I power on?
Q2:It's made a stand-by mode after register setting. When doing wake-up after that, is time until a result of measurement goes out also same?
Thanks for your post. So for your first question, the 1.1 ms here is the minimum time (from power on to Standby) you need to wait before accessing the registers. 1.1ms + 1/ODR guarantees the valid output for ADXL375 from Standby to Measurement mode. If you are running at 3200Hz ODR, then 1.4ms is needed. Wake up mode is a transition between Standby and Measurement mode, so the same principle applies.
You can also refer to the Endnote 7 for Table 1. on the datasheet as well as AN1077 for more detailed information.
I hope this helps.
Thank you for your answer
