[讨论]关于TWI传输的一段代码分析

最近看了一个TWI主模式发送的程序，
void TWI_MasterMode_Write(unsigned short DeviceAddr, unsigned char *TWI_Data_Pointer, unsigned short Count, unsigned short TWI_Length)
{
int i, j;

    *pTWI_FIFO_CTL = 0;    
*pTWI_CONTROL = TWI_ENA | PRESCALE_VALUE;  
*pTWI_CLKDIV = ((CLKDIV_HI) << 8) | (CLKDIV_LO);
*pTWI_MASTER_ADDR = DeviceAddr;      
for (i = 0; i < Count; i++)
{
    
  *pTWI_XMT_DATA8 = *TWI_Data_Pointer++;
  ssync();
  
  *pTWI_MASTER_CTL = (TWI_Length<<6) | MEN ;
  for (j = 0; j < (TWI_Length-1); j++)
  {
      
   while (*pTWI_FIFO_STAT == XMTSTAT)  
    ssync();
   *pTWI_XMT_DATA8 = *TWI_Data_Pointer++;  
   ssync();
  }
  while ((*pTWI_INT_STAT & MCOMP) == 0)  
   ssync();
  *pTWI_INT_STAT = XMTSERV | MCOMP;    
}
asm("nop;");
asm("nop;");
asm("nop;");
}
感觉少了一句代码，还应该向TWI_INT_MASK写入来使能TWI事件中断，不知道我的看法是否正确？应不应该添加对TWI_INT_MASK寄存器的写入？请大家讨论一下……
