2 About This Document

This document contains reference material for the EZR32HG series of wireless microcontrollers. Allmodules and peripherals in the EZR32HG series devices are described in general terms. Not all modulesare present in all devices, and the feature set for each device might vary. Such differences, includingpin-out, are covered in the device-specific datasheets.

2.1 Conventions

Register Names

Register names are given as a module name prefix followed by the short register name:

TIMERn_CTRL - Control Register

The "n" denotes the numeric instance for modules that might have more than one instance.

Some registers are grouped which leads to a group name following the module prefix:

GPIO_Px_DOUT - Port Data Out Register,

where x denotes the port instance (A,B,...).

Bit Fields

Registers contain one or more bit fields which can be 1 to 32 bits wide. Multi-bit fields are denoted with(x:y), where x is the start bit and y is the end bit.

Address

The address for each register can be found by adding the base address of the module (found in the Memory Map), and the offset address for the register (found in module Register Map).

Access Type

The register access types used in the register descriptions are explained in Table 2.1 (p. 3) .

　　智能晾衣架是在传统晾衣架上改良而来的手摇晾衣架。它通过对电路板I/O口的通断控制照明、杀菌、风干等功能的实现，以及电机的正、反转从而实现衣杆的上升、下降等功能。

　　自二十世纪来随着国内经济高速发展及房地产的快速扩张，直接促进了装修家居行业飞速发展，其中晾衣架 市场已顺势脱颖而出，十年间得以迅猛发展。智能晾衣架作为一个独立的行业，逐步由起步阶段慢慢成熟。

　　由于手摇晾衣架本身存在构造简陋，使用寿命短、保养繁琐等种种缺陷，无法满足消费者日益发展的家居智能化需求。原始的晾衣架是只有一根绳子或者铁丝到穿一根钢管，之后出现了尼龙绳拉着升降，后来又发明了尼龙绳式手摇晾衣架，八九十年代，晾衣架进化到了钢丝手摇式。以欧科臻品为首的电动晾衣架迅速占领了整个国内市场的集成吊顶领域 。

　　晾衣架主要分为手摇晾衣架、电动晾衣架两种类型，电动(以欧科臻品晾衣架为主流品牌)方式发展较为迅速;集成吊顶主要分为铝扣板吊顶、绿可木(生态木)吊顶，安装方式分为内装式(嵌入式安装)、外装式两种。

　　近年来，由于家庭装修方面大多数家庭阳台都采用集成吊顶，这就产生了将电动晾衣架与集成吊顶相结合使用的技术，业内比较有代表性的是以欧科臻品晾衣机为主的集成吊顶嵌入式晾衣架，在设计上集成了成熟的一体化设计，隐藏式(嵌入式安装)安装的方式，将晾衣机主机置于吊顶之上，让阳台兼具时尚美观与智能晾衣功能，颠覆了传统阳台的单调与乏味;而且有专门搭配晾衣架的阳台吊顶板材，与阳台墙砖的风格匹配度高，整体外观十分完美。将集成吊顶与晾衣架的智能模块相配合安装使用，不仅具备有集成吊顶的时尚美观、款式新颖及种类的多样性，更是将晾衣架的各种智能模块集成到一起，如遥控自动升降、智能风干、杀菌消毒、LED照明、暖风烘干、蓝牙模块、联网控制等等......
