;* Title        : TELECARD SIMULATION ROUTE
;* Version        : 2.1 (new mode)
;* Last updated        : 99.08.18 /99.10.6 
;* Card Type        : GPM103(Gemplus).SLE4406(Siemens).PCF7960
(Philips)
;*
;* Target        : AT90S2313
;* DESCRIPTION
;*     This program shows how to implement an AT90S2313
;*    as an IC telephony card. 
;*
;*    Port Usage    : PD2(INT0) ---> CLK
;*              PD3(INT1) ---> RST
;*              PD4(T0)   ---> SD
;*    XTAL        : 10MHz
;*
;***************************************************************************
;Ver 99.10.6 
;    1. RST及CLK检测改为中断输入
;    2. 修改擦除过程中读出校验错误的问题(擦除进程ICDATA应右移一位)
(99.10.7)
;    3. RST上升沿使SD变为常高，直至RST下降沿(复位)或CLK下降沿(写/擦除)
;    4. 修正擦除后未清除ERSRDY标志的问题,避免擦除后输出不正确
;Ver 99.10.13
;    1. 仍未解决计费时出错问题,估计写脉冲后输出不对,有待改进
;Ver 99.10.14
;    1.测试:A)加电后,SD端输出为0直至复位后RST下降沿输出
;           B)操作期间,RST正脉冲时SD输出为0,写操作时,RST下降沿输出
;         原位地址数据直至写CLK脉冲下降沿.
;           C)位地址超过103时,SD输出为1,直至位地址超过127时才翻转为0,
    
;         即输出为16字节,后3字节为0xFF
;    2.改正程序以与测试结果相符
;    3.费用数据放入EEPROM
;Ver 99.11.10
;    4.擦除及写入后等待相应时间(4ms)，此段时间不响应
;Ver 00.3.12
;    1.仔细分析了IC卡，可能用紫外光照射会擦除掉IC卡中EEPROM段信息，即利用
光
;    除掉浮栅上的负电荷，仍需实验，“路漫漫其修远兮，吾将上下而求索！”
;    2.2000/3/25 实验,结论: 悲哀----不行  :(  阿门,救救我吧!!!!
;Ver 00.3.28
;    1.将写后延时缩短为2ms，嘻嘻嘻嘻嘻嘻。。哈哈。。。咳咳。。呃。  成
功!!! 
;Ver 00.3.31
;    1.实验，可打通，但第二次计费时错误断线（打一分钟），估计计费操作之间
IC卡
;      已断电,造成数据不符,须加电池试之,也不排除写操作问题
;Ver 01.2.12
;    1.据说电话机内有金属探测器，须测试之  .......
