现在我使用的是DSP DM642，下面程序里的参数设置不知道是什么意思，也查过IIC的DATA SHEET，但也没有给出解释，求助。
I2C_Config SEEDDM642IIC_Config = {&nbsp; &nbsp;
&nbsp; &nbsp; 0,&nbsp;&nbsp;/* master mode,&nbsp;&nbsp;i2coar;&nbsp; &nbsp;&nbsp; &nbsp;*/
&nbsp; &nbsp; 0,&nbsp;&nbsp;/* no interrupt, i2cimr;&nbsp; &nbsp;&nbsp; &nbsp;*/
&nbsp; &nbsp; (20-5), /* scl low time, i2cclkl; */
&nbsp; &nbsp; (20-5), /* scl high time,i2cclkh; */
&nbsp; &nbsp; 1,&nbsp;&nbsp;/* configure later, i2ccnt;&nbsp; &nbsp;*/
&nbsp; &nbsp; 0,&nbsp;&nbsp;/* configure later, i2csar;&nbsp; &nbsp;*/
&nbsp; &nbsp; 0x4ea0, /* master tx mode,&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;*/
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;/* i2c runs free,&nbsp; &nbsp;&nbsp; &nbsp;*/
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;/* 8-bit data + NACK&nbsp; &nbsp;*/
&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;/* no repeat mode&nbsp; &nbsp;&nbsp; &nbsp;*/
&nbsp; &nbsp; (75-1), /* 4MHz clock, i2cpsc&nbsp; &nbsp;&nbsp;&nbsp;*/

其中的参数设置对应的部分，请帮忙
