We need to share one SPI bus with LSM9DS1 and other devices. The problem is that when the CS signal is inactive, the chip expect I2C communication on MOSI/SDA line. What happens if there is a communication with other SPI device and CS signal is inactive? Does the chip recognize it is not I2C communication and remains silent or it starts to meddle into?
I know the I2C interface can be disabled in the registers, but to disable it I first need to communicate with both interfaces active.
