首先解釋下面程序的含義，再談如何轉換
   // Set port functions
            P0FSRH = 0x00;       // P0 selection High
            P0FSRL = 0x00;       // P0 selection Low
            P1FSRH = 0x00;       // P1 selection High
            P1FSRL = 0x00;       // P1 selection Low
            P2FSRH = 0x00;       // P2 selection High
            P2FSRL = 0x00;       // P2 selection Low
