Note Writing an address to the Logical Address Register is typically performed by the resource manager as a part of dynamic addressing. If the address is changed by a write to the Logical Address Register, later accesses must use the new address.
A24 Registers The HP E1418A requires 256 kbytes of A24 address space. The resource manager determines the location in A24 space of the 256 kbytes assigned to the HP E1418A and writes the most significant address lines into the A16 VXI_Offset Register (base + 0616).
