Are LIS2DW12 registers non-volatile?

I want to setup the wakeup configuration registers and then disconnect the accelerometer from an I2C programmer and power source. When the accelerometer is placed with the new circuit, will the configurations in the register I have set still remain? The datasheet does not mention non-volatile memory on registers.

Only the factory-calibrated calibration coefficients are located in non-volatile memory. The registers are all RAM based and therefore volatile.

Does it answer your question?

Thats unfortunate then. Do you recommend any ST alternatives that do have non-volatile memory on registers?

I am not aware of any alternative sensors that realise registers as NVM. This means that a small MCU is always required to feed the registers during power-up.
