LA-MachXO Automotive Family Data Sheet
There are 14 input signals: 13 signals from routing and one from the carry-chain (from the adjacent Slice/PFU).
There are 7 outputs: 6 to the routing and one to the carry-chain (to the adjacent Slice/PFU). Table 2-1 lists the sig-
nals associated with each Slice.
