Characteristics subject to change without notice

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 tWR. 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

two potentiometers and one of its associated

registers; or the transfer can occur between both

potentiometers and one associated register.

Four instructions require a two-byte sequence to

complete, as illustrated in Figure 7. These instructions

transfer data between the host/processor and the

CAT5269; 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.

— Gang XFR Data Register to Wiper Control

Register

This transfers the contents of all specified Data

Registers to the associated Wiper Control

Registers.

— Gang 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 9

and 10). The Increment/Decrement command is differ-

ent from the other commands. Once the command is

issued and the CAT5269 has responded with an ac-

knowledge, 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

SCL clock pulse (tHIGH) while SDA is HIGH, the

selected wiper will move one resistor segment

towards the RH terminal. Similarly, for each SCL clock

pulse while SDA is LOW, the selected wiper will move

one resistor segment towards the RL terminal.

See Instructions format for more detail.
