controlled by the Wiper Counter Register (WCR). The
six bits of the WCR are decoded to select, and enable,
one of sixty-four switches.
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.
Device Addressing
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].
Figure 1. Slave 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
A0 - A3 inputs can be actively driven by CMOS input
signals or tied to VCC or VSS.
Acknowledge Polling
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.
Flow 1. ACK Polling Sequence
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 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.
