9.5.2.2 Writing the Configuration Register

Write the configuration register as shown in Figure 13 using a single I2C communication frame. The R/W bit at the end of the salve address is 0 to indicate a write. The host first sends the register pointer that points to the configuration register, followed by two bytes that represent the register content to write. The TLA202x acknowledge each received byte.
