(1) The I2C address is linked to the selected start-up voltage. The user cannot select the start-up voltage and I2C address independently.
(2) The user can use the VSEL pin to select which of the four start-up voltages the device uses. For more information, see Table 8-5 and Table 8-10.

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