RELIANCE S-25052-3VMEbus內(nèi)存映射本節(jié)描述VMEbus主控器查看的本地資源映射。ENV命令提供從屬、主和GCSR地址解碼器的默認(rèn)地址。請參閱附錄A。VMEbus訪問本地總線VMEcchip2包括用于VMEbus到本地總線接口的用戶可編程映射解碼器。映射解碼器允許您編程開始和結(jié)束地址以及控制器響應(yīng)的修改器。VMEbus短I/O內(nèi)存映射VMEchip2包括用于GCSR的用戶可編程映射解碼器。RELIANCE S-25052-3GCSR映射解碼器允許您在VMEbus短I/O空間中編程GCSR的起始地址。軟件初始化使用其他模塊上的開關(guān)或跳線完成的大多數(shù)功能都是通過在MVME162FX嵌入式控制器上設(shè)置控制寄存器來完成的。在加電或復(fù)位時(shí)，包含162Bug調(diào)試包的EPROM設(shè)置了許多這些寄存器的默認(rèn)值。RELIANCE S-25052-3
VMEbus Memory Map This section describes the mapping of local resources as viewed by VMEbus masters. Default addresses for the slave, master, and GCSR address decoders are provided by the ENV command. Refer to Appendix A. VMEbus Accesses to the Local Bus The VMEchip2 includes a user-programmable map decoder for the VMEbus to local bus interface.RELIANCE S-25052-3 The map decoder allows you to program the starting and ending address and the modifiers the controller responds to. VMEbus Short I/O Memory Map The VMEchip2 includes a user-programmable map decoder for the GCSR. The GCSR map decoder allows you to program the starting address of the GCSR in the VMEbus short I/O space.Software Initialization Most functions that have been done with switches or jumpers on other modules are done by setting control registers on the MVME162FX Embedded Controller. At power-up or reset, the EPROMs that contain the 162Bug debugging package set up the default values of many of these registers.RELIANCE S-25052-3
