i use the gerneral io mode,bue the pin(PIO0_11) is always high.

 

i want to get the low voltage,so the test programs is as follows:

 

LPC_IOCON->JTAG_TDI_PIO0_11 &= ~0x1F;
LPC_IOCON->JTAG_TDI_PIO0_11 |= (1<<4);
LPC_GPIO0->DIR=(1<<11);
LPC_GPIO0->DATA &=~(1<<11);

 

 

but the voltage of pin(PIO0_11) is always high.
