In addition to the device-specific Soft Reset command, the HDC302x-Q1 supports the general call address of the I2C specification. This enables the use of a single command to reset an entire I2C system (provided that all devices on the I2C bus support it). Figure 8-14 shows this command. The general call is recognized when the sensor is able to process I2C commands and is functionally equivalent to the Software Reset.
