Step 2: Peripheral/Slot Assignment

Schematic: available here

Serial host interface on pins:
    Pin 44 (output) : TX from FPGA to host
    Pin 46 (input)  : RX from host to FPGA

Note that the Tang Nano 4K has three voltages for input/output.
Some slots necessarily mix pins with different voltages. Careful!
Some pins on the connectors are used internally and are unavailable.

Slot / Pin Assignments

Slot 1: 43 42 41 40

Slot 2: 39 35 34 32

Slot 3: 31 33 16 13

Slot 4: 17 18 19 20

Slot 5: 21 22 23 27

Slot 6: 28 29 30


Slot 0 is already assigned to the input/output devices on the FPGA board.
