-- To access these locations the VME Master should left shift these addresses of two or three
-- bits according with the wb data bus width which can be 32 or 64 bits.
-- for example: we want write 1 in the ier register (irq_0 enabled):
-- if g_width = 32 --> A32_S access to the VME address 0x04
-- if g_width = 64 --> A32_S access to the VME address 0x0c
-- if g_wb_data_width = 32 --> A32_S access to the VME address 0x04
-- if g_wb_data_width = 64 --> A32_S access to the VME address 0x0c
-- g_width refers to the wb data bus width and to the memory and registers width.
-- See also the "Data organization in VME and WB bus" section of the vme64x_user_manual
-- The irq lines are drived by two counters.
