3.2 DEVICE ADDRESSING

The VMIVME-2131 is designed to support data transfers in supervisory or

nonprivileged short I/O memory space. Jumpers are provided, as shown in Figure
3.2-1 (Address Selection Block Diagram), to allow user selection of either I/O access
type. These jumpers are called AM2. There is one jumper for the Data Registers and
one jumper for the CSR. The VMIVME-2131 is factory configured (jumpers AM2 not
installed) to respond to short supervisory I/O access.
