STLC60134S
DIGITAL INTERFACE
Control Interface
The digital setting codes for the STLC60134S configuration are sent over a serial line (CTRLIN) using
the word clock (CLWD).
The data burst is composed of 16 bits from which the first bit is used as start bit (’0’), the three LSBs be-
ing used to identify the data contained in the 12 remaining bits. Test related data are overruled by the
normal settings if the TEST pin is low.
