Address values specified in the command file are word addresses as interpreted
by the bus controller, not the byte addresses used by PCI. The command below
would write 16-bit words 0800 and 0001 hex to bus controller address 0100 and
0101 hex.
MEM #0100 #0800 #0001
It will actually write the 0800 hex to the PCI address 0200 hex, and 0001 hex to
PCI address 0202 hex. If this was a message list the LISTPTR register should
be programmed with 0100 hex. When started the bus controller will process a
message descriptor from word address 0800 hex. The message descriptor is
stored at PCI address 1000 hex.
