2.產(chǎn) 品 詳 情 資 料：
具體編程細(xì)節(jié)可參考M68040微處理器用戶(hù)手冊(cè)確定。然后檢查RELIANCE 45C225嵌入式控制器編程器參考指南中給出的所有控制器板載寄存器的詳細(xì)信息。多MPU編程注意事項(xiàng)良好的編程實(shí)踐表明，一次只能有一個(gè)MPU控制MVME162FX的控制寄存器。特別值得注意的是：RELIANCE 45C225? 修改地址映射的寄存器? 需要兩個(gè)周期才能訪問(wèn)的寄存器? VME總線中斷請(qǐng)求寄存器本地復(fù)位操作本地復(fù)位（LRST）是系統(tǒng)復(fù)位（SRST）的一個(gè)子集?？赏ㄟ^(guò)五種方式生成本地重置：? 看門(mén)狗定時(shí)器到期? 按下前面板復(fù)位開(kāi)關(guān)（如果系統(tǒng)控制器功能被禁用）? 通過(guò)在GCSR的板控制寄存器中聲明一位? 通過(guò)SYSRESET*? 通過(guò)加電復(fù)位RELIANCE 45C225
Specific programming details may be determined by referencing the M68040 Microprocessor User’s Manual. Then check the details of all the controller’s onboard registers as given in the RELIANCE 45C225 Embedded Controller Programmer’s Reference Guide. Multi-MPU Programming Considerations Good programming practice dictates that only one MPU at a time have control of the MVME162FX’s control registers. Of particular note are: ? Registers that modify the address map ? Registers that require two cycles to access ? VMEbus interrupt request registers Local Reset Operation Local reset (LRST) is a subset of system reset (SRST). Local reset can be generated five ways: ? Expiration of the watchdog timer ? Pressing the front panel RESET switch (if the system controller function is disabled) ? By asserting a bit in the board control register in the GCSR ? By SYSRESET* ? By power-up resetRELIANCE 45C225
