* Not in Slice 3
For Slices 0 and 2, memory control signals are generated from Slice 1 as follows:
WCK is CLK
WRE is from LSR
DI[3:2] for Slice 2 and DI[1:0] for Slice 0 data
WAD [A:D] is a 4bit address from slice 1 LUT input
FCO from Slice/PFU, FCI into Different Slice/PFU
A0, B0, C0, D0
A1, B1, C1, D1
