前言

在H8 / 534和H8 / 536是高性能的单芯片日立独创的微型计算机，

配备了高速CPU与16位内部数据通道和片上的全套

支持模块。它们是理想的微控制器为各种各样的中等规模的装置，

包括办公设备和工业设备和消费电子产品。

该CPU具有通用寄存器结构。它的指令集是高度正交性，

快速执行的编码在高级的C语言程序进行优化。为了进一步加快，

现有的10 - MHz的阵容已经扩展到包括在运营的高速版本

16兆赫。 ，在3 V和2.7 V电源供电的低电压版本也已开发。

片内的设施包括大容量的RAM和ROM的记忆，无数的定时器，串行I / O ，一个A / D

转换器， I / O端口和其它功能的紧凑型实现高性能

应用系统。

H8 / 534和H8 / 536是既ZTAT 版本*带有片上PROM ，非常适合

生产或产品频繁变化的规格初期阶段，和一个masked-

ROM版本适用于批量生产。

本手册给出了H8 / 534和H8 / 536的硬件描述。对于该指令的细节

集，指的是

H8 / 500系列编程手册，

它适用于在H8 / 500所有的芯片

系列。
