RELIANCE 0-51847-1尺寸近似。4.緩存抑制取決于映射區(qū)域中的設(shè)備。5.PROM和Flash的大小由MC2芯片ASIC從8位專(zhuān)用總線到32位MPU本地總線確定。由于某些條目的設(shè)備大小小于分配的內(nèi)存映射大小，因此這些條目的設(shè)備內(nèi)容會(huì)重復(fù)。如果安裝了跳線GPI3，則可以訪問(wèn)閃存設(shè)備。如果未安裝GPI3，則可訪問(wèn)PROM。6.閃存和PROM的大小由MC2芯片ASIC從8位專(zhuān)用總線到32位MPU本地總線確定。RELIANCE 0-51847-1由于某些條目的設(shè)備大小小于分配的內(nèi)存映射大小，因此這些條目的設(shè)備內(nèi)容會(huì)重復(fù)。如果安裝了跳線GPI3，則可訪問(wèn)PROM。如果未安裝GPI3，則訪問(wèn)閃存設(shè)備。7.除非可編程解碼器之一被初始化以解碼該空間，否則這些區(qū)域不被解碼。如果它們未被解碼，則對(duì)該地址范圍的訪問(wèn)將生成本地總線超時(shí)。必須啟用本地總線計(jì)時(shí)器。下表重點(diǎn)介紹本地總線主內(nèi)存映射的本地I/O設(shè)備部分。RELIANCE 0-51847-1
Size is approximate. 4. Cache inhibit depends on devices in area mapped. 5. The PROM and Flash are sized by the MC2 chip ASIC from an 8- bit private bus to the 32-bit MPU local bus. Because the device size is less than the allocated memory map size for some entries, the device contents repeat for those entries. If jumper GPI3 is installed, the flash device is accessed.RELIANCE 0-51847-1 If GPI3 is not installed, the PROM is accessed. 6. The Flash and PROM are sized by the MC2 chip ASIC from an 8- bit private bus to the 32-bit MPU local bus. Because the device size is less than the allocated memory map size for some entries, the device contents repeat for those entries. If jumper GPI3 is installed, the PROM is accessed. If GPI3 is not installed, the flash device is accessed. 7. These areas are not decoded unless one of the programmable decoders are initialized to decode this space. If they are not decoded, an access to this address range will generate a local bus timeout. The local bus timer must be enabled. The following table focuses on the Local I/O Devices portion of the local bus main memory map.RELIANCE 0-51847-1
