8. TION 3 1 GENERAL The VX405C carrier provides a mechanical and electrical interface between a VXIbus system and up to six ANSI VITA 12 1996 standard M MA modules The carrier provides VXI register configuration and access to the M MA module s I O Space and Memory if present Each M MA is controlled separately and appears as a different logical address in the VXI environment A simplified block diagram of the module is shown in Figure 2 The VX405C has no logical address or programmable registers associated with it thus allowing the carrier to be completely transparent in the VXI system VXI I F M MA Module VE amp VXI A Registers M MA M MA Module Module E I F amp VXI VF amp VXI B Registers Registers VF 8 VXI I F 8 VXI Registers Registers I F amp VXI Registers Figure 2 Functional Block Diagram 3 2 INTERFACES The six M MA locations interface electrically and mechanically with industry standard M MA modules meeting the ANSI VITA 12 1996 M Module Specification approved May 20 1997 Each M MA has its own I O connector and is accessible through the front panel of the VX405C via the connector or a user provided cable 3 3 IO AND MEMORY ADDRESSING The VX405C supports D8 Even Odd D16 and D32 data access as well as A16 A24 and A32 addressing The VXI registers of the M MAs are accessible in t

VXI Device Type register 0x02 The default Required Memory setting is the minimum amount allowed by the VXI address space selected A24 addressing allows a minimum of 512 bytes and A32 addressing allows a minimum of 64Kbytes Note In order to access the M MA Module IO Space and memory the AAA bit in the VXI Status Control register 0x04 must be set high This is usually done by the resource manager after allocating memory For M Modules that have only IO Space 256 bytes the default Required Memory setting is sufficient and no changes to this field are required For MA Modules that have on board memory the Required Memory field must be changed to cause the resource manager to allocate enough memory space for the IO Space and memory contained on the MA Module Since the VX405C maps a MA Module s IO Space into the lowers 256 bytes of the allocated memory space and the MA Module s memory into the upper half of the allocated memory space the VXI Required Memory must be set to twice the MA Modules required memory For example if an MA Module has 512Kbytes of on board memory then 1Mbyte of VXI memory space must be allocated The modules 256 bytes of IO Space is mapped starting at the Offset 0x000000 A24 and the 512Kbytes of memory begins at the Offset 0x080000 A24 Proper settings are given in the table provided under the VXI Device Type register description in Figure 6 To change the Require Memory field simply write the new
