The WREG command writes data to a single register. The single register write command is a two-byte command containing the address and the data to write to the address. The command details are shown below:
First byte: 010a aaaa, where a aaaa is the register address.
Second byte: dddd dddd, where dddd dddd is the data to write to the address.
The resulting command status response is a register read back from the updated register. An example of a single register write and response is shown in Figure 77.
