Try this. You need to fill in the truth table. Each byte (pair of hex digits) represents the Slot.

01 = Use code on that slot.
00 = Don't use code on that slot.

LL = Slot 0
NN = Slot 1
PP = Slot 2
QQ = Slot 3
RR = Slot 4
SS = Slot 5
TT = Slot 6
UU = Slot 7
VV = Slot 8
XX = Slot 9
YY = Slot A
ZZ = Slot B
