EN
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.

DA
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.
