Figure 8 Primary VME A24/A32 Memory Map

Note: The full A24 memory map occupies one-quarter of the available A24 space. This can be reduced to the standard 512K (16M ÷ 32) of the available A24 space by mapping only the lower 512 Kbytes (128k x 32) of the global shared SRAM. This is entirely programmable in the SCV64 base address registers. Only SCV64 A21 and A20 are used for decode on SCV64 VME slave accesses to the board. D16 and D08E0 writes are not supported on the primary A32/A24 interface.

4.3.A24 Secondary Slave Interface

Jumper block JP1 sets address bits A23..A17 of the VME A24 slave interface. This base address defines a 128K byte addressed memory space accessed by the VME bus. Access to this space from the VME bus bypasses the SCV64 VME bus interface chip.

All A24 VME transfer types are accepted except for LOCK, and MBLT types.

As shown in the following memory map, the A24 slave interface provides the VME bus direct access to:

∙The Host Port Interface (HPI) registers of each ‘C6x processor

∙The Test Bus Controller (TBC) for JTAG debugging operation

∙Control and Status registers of the Monaco board

D16 and D08E0 accesses are not supported on the slave A24 secondary interface.
