Hi.

I'm trying to drive R_ PIO1_1in my board as GPIO (output)  but I can't: I tried many configuration but this pin remain pulluped to 3,3V .even if I disable internal pullup/down
Here is my code: what am I forgetting?


LPC_IOCON->R_PIO1_1  &= ~0x8F;
    LPC_IOCON->R_PIO1_1 |= 0x01;
     LPC_IOCON->R_PIO1_1           &= ~(0x10);

GpioSetDir(PORT1,1,1):


Thank you
