1.
If using separate supplies for
VA and VD, 5.1 Ω resistor not
needed. See "Grounding and
Power Supply Decoupling."
2. _{Use a 47 kΩ pull-down to select}
Master Mode or 47 kΩ pull-up to
VD to select Slave Mode. See
"Master/Slave Mode Selection."
3.
Use pull-up resistors in Software
Mode. In Hardware Mode, use
pull-up or pull-down. See "Mode
Selection & De-Emphasis."
