3-Wire bus input:

Enable

Enable input of the serial

control interface with

Schmitt-Trigger input

stage. When EN=H the

input signals CLK and DA

are disabled. When EN=L

the serial control interface

is enabled. The received

data are transferred to the

registers with the positive

edge of the EN-signal.

3-Wire bus input: Data

Data input of the serial

control interface with

Schmitt-Trigger input

stage.The serial data are

read into the internal shift

register with the positive

edge of CLK.
