First slice

Because making discrete clocks is not an end in itself.

So one latch "building block" is this :

BOM:

A "slice" is a "DFF and a half" : one master latch and two slaves, one of them can be connected to the processor.

This is pretty easy to place & route on a small board.

In this example, the "slice" is configured for the receive circuit (SIPO). The 3 latches must be connected differently to perform the PISO function, so each "slice board" would have each individual latch connected to the outside so a backplane can configure the correct function.
