标题：Soloman:W77E58+RTL8019,不能对RTL8019的IMR和PAR0~PAR5不能操作
摘要：No.4808W77E58+RTL8019,不能对RTL8019的IMR和PAR0~PAR5不能操作 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 */
RTLPage(1);
WriteReg(1,0x00);
WriteReg(2,0xe0);
WriteReg(3,0x19);
WriteReg(4,0x21);
