time.c

自己编写的bootloader for S3c4510. 1、支持串口下载

#include "Main.h"

void Init_Time(unsigned int channel)
{
   if(channel==0)
   {
     Enable_Int(nTIMER0_INT);
     TMOD=0x3;
     TDATA0=50000000>>2;     //50Mʱ0.25S
     Enable_Int(nTIMER0_INT);
   }
   else
   {
   }
}
void Time0_interrupt(void)
{
  if(IOPDATA&0x2)  IOPDATA&=0x0D;
  else             IOPDATA|=0x02;
  if(Uart_receiving_file == TRUE)  Time0_count++;
}
