IC卡操作软件:AT88SCl604芯片的操作模式有五种。它们是通过配PGM、RST、CLK等引脚信号及内部地址计数器(IAC)的状态组合来实现。 (1) 芯片复位操作： AT88SCl604有两种复位方式:上电复位和控制复位。 上电复位： 上电复位是当芯片加电时的最初状态。上电复位属于芯片 内部复位。它将使芯片内部所有的隐含标志复位到"0"状态。并使地址计数器复位到0位。 控制复位： 当CLK为低时，在RST脚上的一个下降沿将便芯片产生复位操作。 控制复位是将地址计数器复位到0位，而不影响任何内部标志的状态。-IC Card operating software : AT88SCl604 chip mode of operation there are five. They are allocated by PGM, RST, etc. pin CLK signal and the internal address counter (IAC) portfolio of the state is to be achieved. (1) chip reset operation : reduction AT88SCl604 two ways : power-on reset and reset control. Power-on reset : power-on reset when the chip is in power at the initial state. Power-on reset the internal chip is reset. It will enable all internal chip implied signs reset to "0" state. Make address counter reset to 0. Reset control : When the CLK for the low, the RST feet of a falling edge chips will have to reset operation. Reset control is to address counter reset to 0, without prejudice to any signs of internal sta

该设备是一款基于AVR mega16L单片机的电子书阅读器，它除具有传统的阅读电子资源功能外，还能通过PS2接口与PC键盘连接，使用普通PC键盘输入信息，进行文本录入；使用LCD12864液晶作为显示器，它还可以用VB专门为之编写的下载软件通过串口下载TXT格式的文本资源。电子书资源存储在AVR公司生产的AT45DB021B闪速存储器，它有2M存储空间，可满足一般用户需要，当然也可升级为大容量存储器。 该设备功能强大，将电子书阅读器发挥到了极致，能满足用户特殊需要。 -The device is a single chip based on the AVR mega16L e-book reader, which in addition to the traditional functions of reading electronic resources, but also through the PS2 interface to connect with the PC keyboard, use an ordinary PC keyboard input information, the text input use LCD12864 LCD as a display, it can be prepared by specialized VB download software through the serial port to download TXT format text resources. E-book resources are stored in the AVR produced AT45DB021B flash memory, it has 2M storage space to meet the needs of general users, of course, can also be upgraded to a large-capacity memory. The device is powerful and will play an eBook reader to the extreme, and to meet the special needs of users.
