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.

Flow 1. ACK Polling Sequence

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.

START

Device Addressing

Issue Slave

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

Proceed

Instruction Structure

The next byte sent to the X9409 contains the

instruction and register pointer information. The format

is shown in Figure 2.

A - A inputs can be actively driven by CMOS input

signals or tied to V

or V

Acknowledge Polling

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.

R1 R0

P1 P0

Pot Select

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.
