7.5.4 I2C Register Reset
The I2C registers can be reset by:
• Pulling the input voltage below 1.4V (typical).
• Setting the RESET bit in the CONTROL register. When RESET = 1, all registers are reset to the default
values and a new start-up begins immediately. After td(EN)2, the user can program the I2C registers again.
