The TPS652353 requires a start condition, a valid I²C address, a register address byte, and a data byte for a single update. After the receipt of each byte, TPS652353device acknowledges by pulling the SDA line low during the high period of a single clock pulse. TPS652353 performs an update on the falling edge of the LSB byte.

When the TPS652353 is disabled (EN pin tied to ground) the device cannot be updated via the I²C interface.
