8.5.2.2 Writing the Configuration Register

Write the Configuration register (as shown in Figure 8-10) using a single I2C communication frame. The R/W bit at the end of the target address is 0b to indicate a write. The host first sends the Address Pointer register that points to the Configuration register, followed by two bytes that represent the register content to write. The ADS111xL acknowledge each received byte.
