2.产 品 详 情 资 料：
RELIANCE 45C200A I/O处理器模块地图的许多区域是用户可编程的，表中显示了建议的用途。缓存抑制功能可在MC68xx040 MMU中编程。板载I/O空间必须标记为缓存禁止并在其页表中序列化。表1-5进一步定义了本地I/O设备的映射。复位启用了存储器映射的这个空间的解码器，RELIANCE 45C200A I/O处理器模块以便它将解码地址空间。在启用DRAM之前，必须在MC2芯片中禁用0处的解码。DRAM通过地址位24处的DRAM控制寄存器被启用。PROM/Flash在具有PROM控制寄存器的低地址空间被禁用。该区域是用户可编程的。DRAM和SRAM解码器在MC2芯片中编程，本地到VMEbus解码器在VMEchip2中编程，IP存储器空间在IP2芯片中。RELIANCE 45C200A
RELIANCE 45C200AMany areas of the map are userprogrammable, and suggested uses are shown in the table. The cache inhibit function is programmable in the MC68xx040 MMU. The onboard I/O space must be marked cache inhibit and serialized in its page table.RELIANCE 45C200ATable 1-5 further defines the map for the local I/O devices Reset enables the decoder for this space of the memory map so that it will decode address spaces The decode at 0 must be disabled in the MC2 chip before DRAM is enabled. DRAM is enabled with the DRAM Control Register at address bit 24. PROM/Flash is disabled at the low address space with PROM Control Register This area is user-programmable. The DRAM and SRAM decoder is programmed in the MC2 chip, the local-to-VMEbus decoders are programmed in the VMEchip2, and the IP memory space is programmed in the IP2 chip.RELIANCE 45C200A
