How does autodetect work to determine SPI and I2C.

 

Can you confirm ADXL372BCCZ MISO will be tristated when /CS goes HIGH. It is not mentioned in datasheet. 

 

Please bear in mind SPI is undocumented standard (no notified body maintain SPI standard) (unlike I2C, Bluetooth, USB, etc), I seen some device do not tri-state when /CS goes high and it is important to be explicit in datasheet without assumption. I raised this similar query earlier from ADXL355 device.
