Each slave image also includes a programmable address offset. The offset is added to the
VMEbus address, and the result is used as the PCI/X bus address.

the offset in the Inbound Translation Offset Lower (ITOFLx) register (see
Section 10.4.51 on page
If the VMEbus address is 32-bits, then the incoming VMEbus address bits 63 to 32 are
forced to zero and then bits 31 to 0 of the offset in the ITOFUx register and bits 31 to 16
of the offset in the ITOFLx register are added to VMEbus address bits 31 to 16.
If the VMEbus address is 24-bits, then the incoming VMEbus address bits 63 to 24 are
forced to zero and then bits 31 to 0 of the offset in the ITOFUx register and bits 31 to 12
of the offset in the ITOFLx register are added to VMEbus address bits 23 to 12.
If the VMEbus address is 16-bits, then the incoming VMEbus address bits 63 to 16 are
forced to zero and then bits 31 to 0 of the offset in the ITOFUx register and bits 31 to 4 of
the offset in the ITOFLx register are added to VMEbus address bits 15 to 4.
