Hi everyone,

I have a lpcxpresso for LPC1114. I'm trying to get the clkout pin given me main clock signal. It looks pretty easy in user manual. There is almost nothing to adjust. But I couldn't do it. Let me explain what I have done;

[SIZE=2]  LPC_IOCON->PIO0_1 &= ~0x07;
  LPC_IOCON->PIO0_1 |= 0x01;
//  GPIOSetDir(0, 1, OUTPUT );
  LPC_SYSCON->CLKOUTCLKSEL = 0x00;
  LPC_SYSCON->CLKOUTUEN = 0x01;  /* Update clock */
  LPC_SYSCON->CLKOUTUEN = 0x00;  /* Toggle update register once */
  LPC_SYSCON->CLKOUTUEN = 0x01;
  while ( !(LPC_SYSCON->CLKOUTUEN & 0x01) );  /* Wait until updated*/[/SIZE]
[SIZE=2][/SIZE]
Where am I doing wrong? Is it something to do with LPCLink?

[SIZE=2][SIZE=3]Thanks.[/SIZE]
