Chip select operation on MEMS sensor ISM330DLC and others.

Hello,I'm just looking at the CS pin operation of ISM330DLC and other ST mems sensors. It seems the when (CS=1) its in I2C mode. When (CS=0) its in SPI mode.Where I'm using multiple devices on an SPI channel with a sepearate CS for each device, what ...
