| When powered, the ADXL367 is in Standby mode by default. It is recommended to confirm the validity of a communication sequence by reading the DEVID_AD register (Address 0x00). The DEVID_AD register is read-only, and contains the value 0xAD. If the data read from DEVID is not 0xAD, it indicates that either the physical connection or command sequence is incorrect. | When powered, the ADXL367 is in Standby mode by default.
