对RTL8019初始化时，代码如下：
unsigned char xdata chRTLInitTmp;
    unsigned int i;
            //在RSTDRV从高电平回到低电平之后的100MS时，在对RTL8019做读写操作，以确保完全复位
        P35 = 1;
    for(i = 0;i < 400;i++);
    P35 = 0;
    for(i = 0;i < 4000;i++);

    /* reset: write to reset prot */
        WriteReg(0x18,0xaa);
        chRTLInitTmp = ReadReg(0x18);
        for(i = 0;i < 20;i++);

    /* init RTL registers*/
        WriteReg(0x00,0x21);
        chRTLInitTmp = 0x00;
        chRTLInitTmp = ReadReg(0x00);

        RTLPage(0);
        WriteReg(0x0a,0x00);    //清RBCR0
        WriteReg(0x0b,0x00);    //清RBCR1
        WriteReg(0x0c,0xe0);    //RCR,监视模式，不接收数据报
        WriteReg(0x0d,0xe2);    //TCR,loopback模式

         WriteReg(0x01,    0x4c);    /* Pstart    */
    WriteReg(0x02,    0x80);    /* Pstop    */
    WriteReg(0x03,    0x4c);    /* BNRY        */
    WriteReg(0x04,    0x40);    /* TPSR        */

        WriteReg(0x07,0xFF);    /* ISR: Interrupt Status Register,write FF to clear up all interrupt status */
        //WriteReg(0x0f,0x00);    /* IMR: Interrupt Mask Register,屏蔽掉所有中断 */

问题在于：当对复位寄存器0x18～0x1f、配置寄存器0x00及其他都操作正常，写进去的数与读出的数相等。但是对IMR(中断屏蔽寄存器)和PAR0~PAR5(物理地址寄存器)不能正常操作。
IMR的问题：执行WriteReg(0x0f,0x00);语句时，直接停止，不向下运行了，但是如果跟到函数里确实正常的，很莫名其妙。
PAR0~PAR5的问题：
执行
         RTLPage(1);
    WriteReg(1,0x00);
    WriteReg(2,0xe0);
    WriteReg(3,0x19);
    WriteReg(4,0x21);
    WriteReg(5,0x68);
    WriteReg(6,0x12);
        for(i = 0;i < 200;i++);
再执行
        chRTLInitTmp = ReadReg(0x01);
        chRTLInitTmp = ReadReg(0x02);
        chRTLInitTmp = ReadReg(0x03);
        chRTLInitTmp = ReadReg(0x04);
        chRTLInitTmp = ReadReg(0x05);
        chRTLInitTmp = ReadReg(0x06);
读出的数根本不是写进去的值。
不知哪里出来问题，向各位高手求助！
