84 VMEbus Addressing
The address modifier generated when the SBus accesses the VMEbus is
determined by the value in the Remote Address Modifier Register. The
programmer should determine which address modifier the target slave
responds to, then write that value to the Remote Address Modifier Register.
Any subsequent memory references to the VMEbus will use this address
modifier. IACK cycles do not use the address modifier lines. The following
table summarizes address modifier codes.
