Write Byte/Word
The first byte of a Write Byte/Word access is the command code. The next 1 or 2 bytes
are the data to be written. When programmed for a Write Byte/Word command, the
Transmit Slave Address, Device Command, and Data0 Registers are sent. In addition,
the Data1 Register is sent on a Write Word command. Software must force the I2C_EN
bit to 0 when running this command. The format of the protocol is shown in
