Characteristics subject to change without notice

The basic sequence of the three byte instructions is

illustrated in Figure 5. These three-byte instructions

exchange data between the WCR and one of the Data

Registers. The WCR controls the position of the wiper.

The response of the wiper to this action will be

delayed by tWRL. A transfer from the WCR (current

wiper position), to a Data Register is a write to non-

volatile memory and takes a minimum of tWR to

complete. The transfer can occur between one of the

four potentiometers and one of its associated

registers; or the transfer can occur between all

potentiometers and one associated register.

Four instructions require a two-byte sequence to

complete, as illustrated in Figure 4. These instructions

transfer data between the host/processor and the

CAT5411; either between the host and one of the data

registers or directly between the host and the Wiper

Control Register. These instructions are:

— XFR Data Register to Wiper Control Register

This transfers the contents of one specified Data

Register to the associated Wiper Control Register.

— XFR Wiper Control Register to Data Register

This transfers the contents of the specified Wiper

Control Register to the specified associated Data

Register.

— Global XFR Data Register to Wiper Control

Register

This transfers the contents of all specified Data

Registers to the associated Wiper Control

Registers.

— Global XFR Wiper Counter Register to Data

Register

This transfers the contents of all Wiper Control

Registers to the specified associated Data

Registers.

INCREMENT/DECREMENT COMMAND

The final command is Increment/Decrement (Figure 6

and 7). The Increment/Decrement command is

different from the other commands. Once the com-

mand is issued the master can clock the selected

wiper up and/or down in one segment steps; thereby

providing a fine tuning capability to the host. For each

SCK clock pulse (t

HIGH) while SI is HIGH, the selected

wiper will move one resistor segment towards the R

H

terminal. Similarly, for each SCK clock pulse while SI

is LOW, the selected wiper will move one resistor

segment towards the R

L terminal.

See Instructions format for more detail.
