Pin 8 can be tied either high or low,

or it can be left unconnected.

Tie SR0 and SR1 high / low

according to spread range desired.

External resistors are not needed to

pull these pins high.

Pin 5 SSON should be left unconnected to turn on

spread spectrum. Pull this pin low to turn spread

spectrum OFF and enable stand-by mode.
