3. TYPICAL CONNECTION DIAGRAMS
* When no external master clock is supplied to the part, both input and output must be set to Slave Mode for the
part to operate properly. This is done by connecting the MS_SEL pin to ground through a resistance of 0 Ω to 1 k Ω
+ 1% as stated in
on page
** The connection (VL or GND) and value of these two resistors determines the mode of operation for the input
and output serial ports as described in
1 kΩ
