EMERSON KJ3241X1-EA1冗余串行接口接線端子
I2C接口路由至P2連接器，以訪問(wèn)位于轉(zhuǎn)換模塊上的串行EEPROM。用戶可使用配置開關(guān)選擇轉(zhuǎn)換模塊串行EEPROM的設(shè)備地址。有關(guān)開關(guān)的信息，請(qǐng)參閱第5章，轉(zhuǎn)換模塊。有關(guān)編程信息，請(qǐng)參閱MVME7100單板計(jì)算機(jī)程序員參考。系統(tǒng)內(nèi)存MC864xD包括兩個(gè)內(nèi)存控制器。MVME7100在每個(gè)控制器上支持一組存儲(chǔ)器。MVME7100支持512MB、1GB和2GB DDR2 SDRAMS。這提供了1GB、2GB和4GB的內(nèi)存配置。MVME7100支持高達(dá)DDR533的內(nèi)存速度。4.6 MVME7100的定時(shí)器計(jì)時(shí)功能由集成在MC864xD中的四個(gè)全局高分辨率定時(shí)器以及四個(gè)額外的獨(dú)立32位定時(shí)器提供。四個(gè)集成32位計(jì)時(shí)器由RTC輸入計(jì)時(shí)，RTC輸入由1MHz時(shí)鐘驅(qū)動(dòng)。有關(guān)更多詳細(xì)信息和/或編程信息，請(qǐng)參閱第117頁(yè)附錄B“相關(guān)文件和制造商文件”中列出的MC864xD參考手冊(cè)
The I2C interface is routed to the P2 connector for access to the serial EEPROM located on the transition module. The device address for the transition module serial EEPROM is user selectable using the configuration switches. Refer to Chapter 5, Transition Module for information on the switches. For programming information, see the MVME7100 Single Board Computer Programmer’s Reference.System Memory The MC864xD includes two memory controllers. The MVME7100 supports one bank of memory on each controller. The MVME7100 supports 512MB, 1GB and 2GB DDR2 SDRAMS. This provides memory configurations of 1GB, 2GB, and 4GB. The MVME7100 supports memory speeds up to DDR533. 4.6 Timers Timing functions for the MVME7100 are provided by four global high-resolution timers integrated into the MC864xD plus four additional independent 32-bit timers. The four integrated 32-bit timers are clocked by the RTC input which is driven by a 1MHz clock. Refer to the MC864xD reference manual, listed in Appendix B, Related Documentation and Manufacturers’ Documents on page 117 for additional details and/or programming information
