The XMI
To get the address for the DMB32 Device Register (DTYPE), do the
following:
1 From Table 2–5 find XMI node E and take the 2-digit prefix for the
start of that node’s window space (FC or 3C depending upon address
mode).
2 From Table 2–7 find VAXBI node 4 and in column 2 you can see that
the starting address for VAXBI node 4 is xx00 8000.
3 Combine this second number with the 2-digit prefix. You now have the
adapter’s base address (FC00 8000) in VAXBI address space, indicated
by lowercase bb.
4 From Table 2–8, VAXBI Registers, you can see that the VAXBI Device
Register (DTYPE) is at bb + 00, which is FC00 8000.
The Device Register for the DMB32 would be examined by:
>>> E/L/P FC008000 ! 32-bit address
>>> E/L/P 2C008000 ! 30-bit address
