X9409  
controlled by the Wiper Counter Register (WCR). The  
six bits of the WCR are decoded to select, and enable,  
one of sixty-four switches.

Nonvolatile Write  
Command Completed  
Enter ACK Polling  
The WCR may be written directly, or it can be changed  
by transferring the contents of one of four associated  
Data Registers into the WCR. These Data Registers  
and the WCR can be read and written by the host  
system.

Address  
Following a start condition the master must output the  
address of the slave it is accessing. The most  
significant four bits of the slave address are the device  
type identifier (refer to Figure 1 below). For the X9409  
this is fixed as 0101[B].

Device Address  
The next four bits of the slave address are the device  
address. The physical device address is defined by  
the state of the A0 - A3 inputs. The X9409 compares  
the serial data stream with the address input state; a  
successful compare of all four address bits is required  
for the X9409 to respond with an acknowledge. The

Instruction Structure  
The next byte sent to the X9409 contains the  
instruction and register pointer information. The format  
is shown in Figure 2.

Figure 2. Instruction Byte Format  
The disabling of the inputs, during the internal  
nonvolatile write operation, can be used to take  
advantage of the typical nonvolatile write cycle time.  
Once the stop condition is issued to indicate the end of  
the nonvolatile write command the X9409 initiates the  
internal write cycle. ACK polling can be initiated  
immediately. This involves issuing the start condition  
followed by the device slave address. If the X9409 is  
still busy with the write operation no ACK will be  
returned. If the X9409 has completed the write  
operation an ACK will be returned and the master can  
then proceed with the next operation.

Instructions  
The four high order bits define the instruction. The  
next two bits (R1 and R0) select one of the four  
registers that is to be acted upon when a register  
oriented instruction is issued. The last bits (P1, P0)  
select which one of the four potentiometers is to be  
affected by the instruction.
