BQ25050的问题

void SEND_OF_PULSES(uint8 cnt)
{
  uint8 iw = 0;
 
  if ( cnt > 16 )//脉冲不能大于16
    return;
 
  for ( iw = 0; iw < cnt; iw ++ )
  {
    CTRL = 1;
    Delay_nUS(THI);
    CTRL = 0;
    Delay_nUS(TLO);
  }
  CTRL = 0;
  Delay_nUS(2000);//低电平延时超过2MS，以上脉冲即发出  
}

void main()

{

      CTRL = 0;             //CTRL is pulled low to enable the device
      Delay_nUS(5000);      //5MS
      //the IC enters the 32ms WAIT state
      CTRL = 1;             //0->1:Rising Edge is Detected
      Delay_nUS(1500);      //1.5MS
      CTRL = 0;             //1-->0:Falling Edge is Detected
      //Increment Pulse Counter
      Delay_nUS(1500);      //Begin 1.5ms LATCH Timer
      //Rising Edge is not Detected after 1.5ms LATCH Timer Expired
      SEND_OF_PULSES( 11 ); //Send Pulse Counter Info to Decode Block

}

这个程序有错误么？我想设置成900ma的
