该产品将基于英特尔的PC和基于摩托罗拉的VMEbus控制器;因此，对“常规”的一些混　　可能存在符号和术语。已尽一切努力制作本手册　通过遵守摩托罗拉/VMEbus世界的典型惯例而保持一致;　

然而，两个阵营的用户都应该查看以下注意事项：十六进制数字为摩托罗拉风格，前缀为美元符号：例如SF79。相比之下，这个相同的数字表示为0F79H根据英特尔惯例，或许多程序员的0xF79。较少的　　常见的形式有F79h或数学家的F7918。●8位的量称为“字节”，16位的量被称为“字”32位的数量被称为“长字”。

尽管它们的32位数量通常被称为“双字”●摩托罗拉程序员应该注意，英特尔处理器有一条I/O总　　完全独立于存储器总线。在通过I/的寄存器和逻辑实体来阐明这一点的手册通过在I/O地址前面加上前缀来填充空间。

因此，“I/O S140”处的寄存器不是与“$140”的寄存器相同，因为后者在内存总　　前者在I/O总线上。

The product will be based on Intel's PC and MOTOROLA's VMEbus controller; Thus, some confusions of "conventional" may exist in symbols and terms. Every effort has been made to produce this manual consistent by adhering to the typical practices of the MOTOROLA /VMEbus world;

However, users in both camps should check for the following caveat: Hexadecimal numbers are MOTOROLA style and prefixed with dollar signs: for example, SF79. In contrast, this same number is represented as 0F79H according to Intel convention, or 0xF79 as many programmers say. Less common forms are F79h or F7918 for mathematicians. 8-bit quantities are called "bytes", 16-bit quantities are called "words" and 32-bit quantities are called "long words".

Although their 32-bit number is often referred to as "double-word", MOTOROLA programmers should note that Intel processors have an I/O that is completely independent of the memory bus. The manual that illustrates this through I/ registers and logical entities fills the space by prefixing the I/O address.

Therefore, the register at "I/O S140" is not the same as the register at "$140" because the latter is in memory and the former is on the I/O bus.
