•8位的量被称为“字节”，16位的量称为“字”，32位的量则称为“长字”。Intel的惯例是类似的，尽管他们的32位量更常被称为一个“双字”。•摩托罗拉程序员应注意，Intel处理器有一条完全独立于内存总线的I/O总线。本手册中已尽一切努力通过引用I/O空间中的寄存器和逻辑实体（通过前缀I/O地址）来阐明这一点。因此，“I/O$140”处的寄存器与“$140”的寄存器不同，因为后者在内存总线上，而前者在I/O总线上。•英特尔程序员应注意，本手册中列出的地址使用的是线性“平面内存”模型，而不是与英特尔实模式编程相关的旧段：偏移模型。因此，位于段：偏移地址C000:0的ROM芯片将在本手册中列为地址$C000000。
• An 8-bit quantity is termed a “byte,” a 16-bit quantity is termed a “word,” and a 32-bit quantity is termed a “longword.” The Intel convention is similar, although their 32-bit quantity is more often called a “doubleword.” • Motorola programmers should note that Intel processors have an I/O bus that is completely independent from the memory bus. Every effort has been made in the manual to clarify this by referring to registers and logical entities in I/O space by prefixing I/O addresses as such. Thus, a register at “I/O $140” is not the same as a register at “$140,” since the latter is on the memory bus while the former is on the I/O bus. • Intel programmers should note that addresses are listed in this manual using a linear, “flat-memory” model rather than the old segment:offset model associated with Intel Real Mode programming. Thus, a ROM chip at a segment:offset address of C000:0 will be listed in this manual as being at address $C0000.
