bits is required for the X9111 to successfully continue the
command sequence. Only the device whose slave address
matches the incoming device address sent by the master
executes the instruction. The A1–A0 inputs can be actively
driven by CMOS input signals or tied to V
R/W bit is used to set the device to either read or write
mode.

Instruction Byte and Register Selection
The next byte sent to the X9111 contains the instruction and
register pointer information. The three most significant bits
are used provide the instruction opcode (I[2:0]). The RB and
RA bits point to one of the four registers. The format is
shown in Table 5.
