unused switch pins

Post by tjm215 » Wed Dec 09, 2015 12:07 pm

is there a best practice when it comes to unused switch pins? should I tie them to ground via 10k resistor or to 3.3v? or does it make no difference (other than the program number)

All switch pins must be used to select a program so they all must be tied high or low accordingly.

Yes, S0-2 tied to ground will select program 0,

s0 = lsb

000 = 0
001 = 1
010 = 2
011 = 3
100 = 4

etc
