Device description

The following non-privileged modes of VME access are possible:

 A24 and A32 in the following VMEbus data formats

 D08 (E0)

 D16

 D32

 A40 MD32 (on special request)

The BLT and MBLT modes as well as the auto-configuration and geo-addressing functions are being prepared, but are not available at this time.

The 2eVME mode has not yet been implemented. Access is only allowed in unprivileged data access mode.

The SM128V is a passive board on the VMEbus, i.e., it will not be actively accessed or interacted with on the VMEbus.

The board uses 256 kbytes of address space on the VMEbus.

Relevant specifications (VITA standards):

 VMEbus

 IEEE 1014-1987

 VME64

 ANSI VITA 1-1994 VME64X; VITA 1.1-19

Remarks Since an analog channel always corresponds to a digital channel in the iba bus concept, 

an analog value and a digital value are referred to as a channel or a signal for simplicity of description.
