I have been using the IIS3DWB evaluation board alongside TIs CC1352P2 uC to bring up software ahead of the actual hardware arriving. The SPI bus speed is 8MHz in mode 3.The IIS3DWB is configured only sample accelerometer data on 3 axis and to store t...

Thanks for the suggestion @Eleon BORLINI With a scope I was able to observe some noise on the Vdd and Vddio lines (see below)With sitting around 3.0V there are times when it could get pulled lower than the 2.1V of the IIS3DWB.When the IIS3DWB is not...
