注意事项
ABB程序员应该注意，英特尔处理器有一个完全独立于内存总线的I/O总线。本手册已尽一切努力澄清这一点，通过在I/O地址前面加上前缀来参考I/O空间中的寄存器和逻辑实体。因此，寄存器“I/O$140”与寄存器“$140”不同，因为后者在内存总线上，而前者在I/O总线上。•英特尔程序员应注意，本手册中列出的地址使用线性“平面内存”模型，而不是与英特尔实模式编程相关的旧段：偏移模型。因此，在本手册中，位于段：偏移地址C000:0的ROM芯片将被列为地址$C0000。为了参考，这里有一些快速转换公式：段：偏移到线性地址线性地址=（段×16）+偏移线性地址到段：偏移段=（（线性地址÷65536）− 余数）×4096偏移量=余数×65536其中余数=（线性地址÷65536）的小数部分注意，有许多可能的段：单个位置的偏移地址。上面的公式将提供一个唯一的段：偏移地址，将段强制到一个偶数64 KB的边界，例如$C000、$E000等。使用此公式时，请确保正确舍入偏移计算！
使用说明
UUD148AE01的硬件跳线设置、连接器说明、安装、系统设置和操作。开箱程序应遵守装运集装箱中的任何预防措施。所有物品都应仔细拆开包装，并彻底检查在装运期间可能发生的损坏。应检查电路板是否有损坏的组件、损坏的印刷电路板、热损坏和其他可见污染。因运输损坏引起的所有索赔应向承运人提交，并向VMIC客户服务部门发送完整的报告，同时请求就损坏物品的处置提出建议。警告：VMIC产品上组装的一些组件可能对静电放电敏感，并且在受到高能静电场的电路板上可能会发生损坏。当电路板放置在工作台上进行配置等时，建议在电路板下方插入导电材料，以提供导电分流。未使用的板应存放在装运时的相同保护箱中。
matters needing attention
ABB programmers should note that Intel processors have an I/O bus that is completely independent of the memory bus. This manual has made every effort to clarify this by prefixing the I/O address to refer to registers and logical entities in the I/O space. Therefore, register "I/O $140" is different from register "$140" because the latter is on the memory bus and the former is on the I/O bus. • Intel programmers should note that the addresses listed in this manual use the linear "plane memory" model, not the old segment related to Intel real mode programming: the offset model. Therefore, in this manual, the ROM chip located at segment: offset address C000:0 will be listed as address $C0000. For reference, here are some fast conversion formulas: segment: offset to linear address linear address=(segment × 16) +Offset linear address to segment: Offset segment=((linear address ÷ 65536) − remainder) × 4096 offset=remainder × The decimal part of 65536 where the remainder=(linear address ÷ 65536) Note that there are many possible segments: offset address of a single position. The above formula will provide a unique segment: offset address, and force the segment to an even 64 KB boundary, such as $C000, $E000, etc. When using this formula, please ensure that the offset calculation is rounded correctly!
instructions
Hardware jumper settings, connector descriptions, installation, system settings, and operation of UUD148AE01. Unpacking procedures should follow any precautions in the shipping container. All items shall be carefully unpacked and thoroughly inspected for possible damage during shipment. The circuit board should be checked for damaged components, damaged printed circuit boards, thermal damage and other visible contamination. All claims arising from transportation damage shall be submitted to the carrier, and a complete report shall be sent to VMIC customer service department, and suggestions on the disposal of damaged items shall be requested. Warning: Some components assembled on VMIC products may be sensitive to electrostatic discharge and may be damaged on circuit boards subject to high energy electrostatic fields. When the circuit board is placed on the workbench for configuration, it is recommended to insert conductive materials under the circuit board to provide conductive shunt. Unused plates shall be stored in the same protective box as shipped.
