W77E58+RTL8019,不能对RTL8019的IMR和PAR0~PAR5不能操作

[Solomne]

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 */
WriteReg(0x0e,0xC8); /* DCR: Data Configuration Register*/

WriteReg(0x0c,0xCE); /* RCR*/
WriteReg(0x0d,0xE0); /* TCR*/

//To debug
chRTLInitTmp = ReadReg(0x07);
chRTLInitTmp = ReadReg(0x0f);

RTLPage(1);
WriteReg(0x07,0x4d); //CURR,设置为指向当前正在写的页的下一页

/* MAR0 */
WriteReg(0x08,0x00);
WriteReg(0x09,0x41);
WriteReg(0x0a,0x00);
WriteReg(0x0b,0x80);
WriteReg(0x0c,0x00);
WriteReg(0x0d,0x00);
WriteReg(0x0e,0x00);
//WriteReg(0x0f,0x00);

/* set phisical address */

WriteReg(6,0x12);
for(i = 0;i < 200;i++);

//To debug
chRTLInitTmp = ReadReg(0x08);
chRTLInitTmp = ReadReg(0x09);
chRTLInitTmp = ReadReg(0x0a);
chRTLInitTmp = ReadReg(0x0b);
chRTLInitTmp = ReadReg(0x0c);
chRTLInitTmp = ReadReg(0x0d);
chRTLInitTmp = ReadReg(0x0e);
//chRTLInitTmp = ReadReg(0x0f);

chRTLInitTmp = ReadReg(0x01);
chRTLInitTmp = ReadReg(0x02);
chRTLInitTmp = ReadReg(0x03);
chRTLInitTmp = ReadReg(0x04);
chRTLInitTmp = ReadReg(0x05);
chRTLInitTmp = ReadReg(0x06);

/* transimit start page */
LastSendStartPage = SEND_START_PAGE0;
StartPageOfPacket = RECEIVE_START_PAGE + 1;

/* in the beginning, no packet is in sending */

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！
