The slave address byte is the first byte received following the START condition from the master device. The first
four bits (MSBs) of the address are factory preset to 1001. The next two bits (A2, A1) of the address are device
option dependent. The LSB bit (A0) is also factory preset to 0. Up to 4 TPS6265x type of devices can be
connected to the same I2C-Bus. See the ordering information table for more details.

Following the successful acknowledgment of the slave address, the bus master sends a byte to the TPS6265x,
which contains the address of the register to be accessed. The TPS6265x contains four 8-bit registers accessible
via a bidirectional I2C-bus interface. All internal registers have read and write access.
