The I2C address is linked to the selected start-up voltage. The user cannot select the start-up voltage and I2C address independently.
The user can use the VSEL pin to select which of the four start-up voltages the device uses.

Unless otherwise noted, device variants without I2C operate with the same default settings as device variants with I2C.
