I am developing a new system with BMP388 sensor. In datasheet (5.1 Interface selection) it says " If CSB is connected to VDDIO, the I2C interface is active" and also in 5.2 I2C Interface section it says "CSB is not used and is left open". It is confused to me. I have only 4 pins for I2C (VDD, GND, SDA and SCL). Then how i must connect CSB pin, connected to VDDIO or floating? I wait for your reply.
