The following example shows a real situation with V767 boards inserted in a VME crate.
The boards are addressed via MCST and CBLT Addressing.
The vme_write and vme_blt_read are two examples of user procedures that contain as
parameters the complete Address (Base + offset), the data (either written or read), the
addressing mode (A24 or A32) and the data mode (D16, D32 or D64).
vme_write(Address, Data, Addr_Mode, Data_mode);
vme_blt_read(Address, Buffer_pointer, Addr_Mode, Data_mode)
