LPC1114 GPIO

In LPC1114 if we configure P0_10,P0_11,P1_0,P1_1,P1_2,P1_3 these pins as GPIO , and toggle simulator wont show changes in status bit , same things happens if we check in actual hardware.
Same snap of code work fine in LPCxpresso.

Please help us to resolve issue
Thanks in Advance

Sorry

Please find code below

#define P1_0    (unsigned short)(1<<0)

int main(void)
{
        SystemInit();
        LPC_SYSCON->SYSAHBCLKCTRL |= (1<<6);

        LPC_IOCON->PIO1_0 &= ~0x07;     //Configure as IO
        LPC_IOCON->PIO1_0 |= 0x01;
        LPC_GPIO0->DIR    |= P1_0;      //Configure as Output
        while(1)
        {
                LPC_GPIO1->DATA &= ~P1_0;        //Clear Bit
                LPC_GPIO1->DATA |=  P1_0;    //Set Bit
        }
}
