Board Addressing
Onboard addressing refers to accessing resources located on the board that is implementing the operation interface (including its modules).
Off-board addressing refers to accessing resources located on another board reachable via VME, PCI, or other bus. Off-board addressing
Motherboard Common Address Space starts at 0x00000000 and ends at 0x00004000. This is a 4Kx32-bit address space (16 kbytes).
Module Address Space starts at 0x00004000. Module addressing is dynamically configured at startup. NAI boards support between 1 and 6
