I'm not able to make it work the GPIO P1.0-P1.3 of LPC1114. Both in hardware as in keil debug the GPIO's P1.0 dont clear.

int main()
{
/* Enable AHB clock to the GPIO domain. */
LPC_SYSCON->SYSAHBCLKCTRL |= (0x1UL << 16);  /* enable clock for IOCON      */
LPC_SYSCON->SYSAHBCLKCTRL |= (0x1UL << 6);  /* enable clock for GPIO      */

LPC_IOCON->R_PIO1_0 |= 0x01;/* P1.0 as GPIO      */
LPC_GPIO1->DIR  |= (1UL <<  0);/* P1.0 as GPIO      */
LPC_GPIO1->DATA &= ~(1UL <<  0);/* Clear P1.0      */ //*********Don't work

while(1);
}

what's wrong with this code?

Nothing :D

Check your setup, especially LPC_IOCON->R_PIO1_0 :O

I have checked the setup and are ok
